NOTE: For trivia buffs. Although the paper is dated 28 May 1986, it was actualy first distributed on 6 June 1986. In my haste to get it out the door, I forgot to change the date. I can do this provided the first batch of requests consists of at least 2 requestors. I have received indications that this will be the case. If there are at least two requests in the first batch, I can do this for $30 per copy, payable in US dollars (no purchase orders as the amount is too small to justify the handling). The $30 price is subject to adjustment anytime on or after 1 January 1994. For non-USA/Canada/Mexico requests, an additional $6.00 is needed for airmail or $2.50 for surface mail. Priority mail in the USA would be an additional $2.90. These additional rates are subject to change if postal rates change. Please send me an email message indicating that you will be making a request so that I may inform you if the postal charges or the price per copy has changed. For the first batch, please send me an email message anyway so I know what to expect. The first batch will be for all payments received by 19 July 1993. I will then procees a batch of requests in two week intervals thereafter. This schedule is subject to modification due to my travel requirements and any unforeseen events such as illness and weather.

If your ftp still hangs, try using a hyphen '-' as the first character of your password.

Sincerely Henry Manaster ------------------------------ Date: Thu, 29 Jul 1993 11:39:58 -0400 From: emory!yu1.yu.edu!manaster (Chaim Manaster) Subject: cdrom security. To: CDPub@knex.via.mind.org I would like to start a discussion that needs much clarification. It relates to the lack of any attention by the publishers of authoring and text retrieval software to the important area of security! That is: if I publish some full text data base, after much effort in compiling and editing and improving it, how do I insure that the data base won't be taken by some client who bought the cdrom, and republished after (perhaps) some minor editing. Keep in mind, that the attack could occur some years down the road, thus security over a long period of time is at issue. I know that there are various copyright (legal) protections that can be invoked, but that is an expensive route to protect ones rights, and in any case, copyright may not always apply. So, I would like to see a thread (comments) about prevention of the above by software (or hardware ?) technology, as a first line of defense, such as encryption and /or compression or any other methedologies such as output limitations or time loops or passwords etc. If any of the software publishers like Folio or KA etc care to comment as to why they have neglected this area, that would be most interesting. Or perhaps they might comment about how in fact they DO meet this need of many cdrom publishers.

To: CDPub@knex.via.mind.ORG Folio, for example, does have security built in. One can refuse printing as a right so that, while a user can screen print, he can't block the entire document and copy that to disk. In reality, I think you have to expect your atorneys to protect you -- just as with print, very few books have been copied and republished even in the age of xerox machines. ------------------------------ Date: Sat, 31 Jul 93 10:12:29 EDT From: Gess Shankar Subject: cdrom security. emory!hq.nasa.gov!JVOGEL writes: > Folio, for example, does have security built in.

If it can be displayed or printed one screen at a time, a determined pirate can extract the information. As always, encryption and copy protection etc. probably hurt the legitimate users more than the determined pirate. > In reality, I think you have to expect your atorneys to protect you -- just a > with print, very few books have been copied and republished even in the age o > xerox machines. Electronic publishing rights will be a big issue in the coming years (if not already). Proper legal protection (where available) will probably be the only recourse available. But piracy is going to be a fact of life, as in software, videos, music etc... which are easier and cheaper to reproduce than books.

First as I announced over this list server (and others) at that time, the vote was successful and I posted the result to news.announce.newgroups at that time. I then expected the rest of the procedure in creating the new newsgroups to follow automatically; i.e., the 5 day wait followed by the creation message fron the moderator to the usenet sites. I had to be out of town (read, away from the internet) immediately after the vote, and have been away for over a month and have just returned. When I got back, I checked for the new groups and found that they had not yet been created! I then emailed the moderator of news.announce.newgroups for info, as to why they had not yet been created. He responded, saying that he had not posted the results, since my RESULT posting was not in "correct format"?? I had posted that RESULT posting to this list-server as well as to others, not realizing that the moderator would not post the "official RESULT." Now that I am back, I am trying to find out what the moderator feels is the "correct format" for the RESULT posting, and will get the process going again as quickly as possible. Sorry for any inconvenience.

Thanks. ------------------------------ Date: Thu, 29 Jul 93 13:00:22 EDT From: Gess Shankar Subject: Multiple Data Tracks I came across a Microsoft CD-Rom (Viewer Toolkit), which appears to have two data track and one CD-DA track. Generally most CD-Roms have one data track and if they are mixed mode CD-Roms, they may have one or more CD-DA tracks following the data track. I found it strange for this CD to have 2 data tracks and 9 second audio track (had a classical music fragment). I am somewhat hazy about what the standards say about this... 2 data tracks. I know XA specs recommend a single XA track, but does allow more than one provided they are grouped together. Now the question. If there is more than one data track, how does one access the second track. Does the directory record for the file point to the second track? Can MSCDEX etc. (in MsDos) access the data in track # 2? Second question to CD.GEN users (if any): How can one create multiple data tracks with the Philips CDD521? Or are there premastering software which allows laying multiple data tracks? [Incidentally: I am guessing that creation of a directory entry pointing to the CD-DA sectors is some sort of copy protection scheme. I don't think that the 9 seconds of music is very relevant to the above cd.] GeSS -- Gess Shankar |<><>| Internet: gess@knex.via.mind.ORG |<><>| CDPub List Admin. |<><>| {rutgers,ogicse,gatech}!emory!uumind!knex!gess |<><>| What is a CDRom? |<><>| 3 billion pits arranged in a 3 mile spiral! |<><>| ------------------------------ Date: Fri, 30 Jul 1993 10:08:14 -0400 (EDT) From: emory!sscl.uwo.ca!DOUG (Doug Link) Subject: Multiple Data Tracks To: CDPub@knex.via.mind.ORG >Second question to CD.GEN users (if any): How can one create multiple >data tracks with the Philips CDD521? Or are there premastering software >which allows laying multiple data tracks? The Philips drive allows you to write multisession discs which are what you call multiple data tracks. Each data track is like a completely self-contained cd-rom, its own lead-in, data section, lead out, toc etc. CD-GEN software caters to this and also provides a ultility called PICKCD which allows you to select the data session when you use the drive as a simple reader. I haven't tried this utility on different drives so I can't vouch for its diversity as yet. A typical mixed mode disc has one data track and one audio track. For example, the Groliers Multimedia Encyclopedia disc is a mixed mode disc. You can actually stick that disc in your audio player and play track two. What you get is classical music out one channel and animal sounds out the other. They obviously packed all their audio clips and filled both channels with what would have otherwise been stereo sound.

Each data track is like a completely I was NOT referring to multisession as multiple data tracks. I was talking about multiple data tracks within the same session.

I have since talked to CD.Rom Strategies (CD.GEN vendors) and have been informed that the CDD521 will in fact make multiple data tracks (within one session) by writing more than one Virtual CD images without fixing and closing the session. When the CD is fixed, the TOC is updated and presto... you have multiple data tracks. How to read the second data track in whole another issue, however. > GeSS -- Gess Shankar |<><>| Internet: gess@knex.via.mind.ORG |<><>| CDPub List Admin. |<><>| {rutgers,ogicse,gatech}!emory!uumind!knex!gess |<><>| What is a CDRom? |<><>| 3 billion pits arranged in a 3 mile spiral! |<><>| ------------------------------ Date: Thu, 01 Jul 93 22:20:46 -0700 From: "Robert A.

To: CDPub@knex.via.mind.org, CDROMLAN@idbsu.idbsu.edu, cdrom-l@uccvma.bitnet Sorry if this is not the precise topic of the list. I have a Pioneer DRM-604x cdrom drive. The player comes supplied with a program (MPC.EXE) that can play the audio disks from any one of the six slots in the magazine. Unfortunately, 1) The program is flakely and often hangs the system 2) The program only works with the Pioneer supplied driver but not with any other driver (which I need to use). 3) The program will not work in Windows, only DOS. 4) MS Media Player (Windows) only can access one of the six slots (the one you select at set up) but no other, thus effectively reducing the drive to a normal (single) cdrom drive. Can anyone direct me to an ftp site (or other source) where I can get other software that will play audio on the Pioneer cdrom drive that does not have these limitations and can access any of the 6 slots at will. I could use such software both for Windows and for DOS as well as OS/2 2.0. Hopefully the software is as full featured as possible (or is that to much to hope for). BTW, I am aware of the player in CORELSCSI software, but am loath to by it just for the audio player, as I don't need any of the drivers at all). Thank you very much for the help.

To: CDPub@knex.via.mind.org G'day again peoples, I've had worrying information that the Sony CDW 900e Desktop CD Mastering system is not physically capable of mastering multi-session CDs. This of course means that a software upgrade alone would be unable to give it this functionality. This conflicts with discussions I had with a representative of CD-Technology at the Apple WorldWide Developer Conference in May. He indicated a software upgrade would be all that'd be needed. Can anyone shed any light on the subject of desktop Multi-Session CD-R recording? Are any of the other units (JVC, Philips etc) capable of it? -Mart ---------------------------------------------------------------------- Martin Hill Internet: chillm@cc.curtin.edu.au Multimedia Consultant QuickMail: Martin_Hill@3517415 Computing Centre AppleLink: AUST0176 Curtin University GPO Box U 1987, Ph:(09)351-3200 Perth 6001, Fax:(09)351-2673 Western Australia ---------------------------------------------------------------------- ------------------------------ Date: Wed, 28 Jul 1993 9:00:36 -0400 (EDT) From: emory!sscl.uwo.ca!DOUG (Doug Link) Subject: Sony CDW 900e Mastering Unit capable of multi-session? To: CDPub@knex.via.mind.ORG I selected the Philips CDD521 over the Sony CDW-900E for this very reason when I was making my own purchasing decision. Sony has certain advantages over Philips but what swayed me to Philips was Sony's inability to do multi-session. On the other hand, Sony can write PCM audio whereas Philips must have it in a special form before it can write it. There are other trade-offs between the two systems, price is another (Philips is cheaper by a few thousand dollars). Philips also makes the Kodak PCD writer, same box actually with a special modification for reading the Kodak bar coded discs, i.e., the bar code is right in the gold reflective layer on the inner most circumference away from the data areas. Hope this helps. Doug Douglas G.

I use CDGen from CD-Rom Strategies, which does provide a translation tool to convert pcm to the philips format. But I would like to investigate writing some in-house tools to do the same. In the same vein: Has anyone been able to read CD-DA sectors from music CDs and write to the Philips CDD521. I lack details on exactly what reading the audio sectors using drives such as the Toshiba 3401 exactly provide? What is involved in reading from a music CD and writing to a CD-R?

As long as you are able to deliver the data rate required by the recorder, there should be no problem. In most cases (especially in the IBM PC compatible world), you have a dedicated PC, with a fairly fast hard disk and CPU, which can deliver the data. Multitasking set-ups and networked units may have problems, though. The Philips unit is normally run on a dedicated SCSI Bus [not sharing with any other peripheral], which ensures that consistant data rates can be assured. For a double speed write operation, it requires slightly more than 300kb/sec and it should not be difficult to keep filling the 256KB buffer.... Here is a feature comparison between the Philips & Sony Units.
