Mastering a CD-ROM

This is for the Young Minds Inc. "CD Studio" hardware, installed on an SGI running IRIX 5.3, with a Philips CDD-521 Compact Disk Recorder (2X speed).

Log in on Whistle, the CD Studio stuff is located there.

Ensure that the CD Studio and the Philips CD-ROM writer are turned on. Ensure that Whistle sees them, by running hinv and looking for this entry:

Tape drive: unit 5 on SCSI controller 0: 8mm(8200) cartridge
Run:
mt -f /dev/rmt/tps0d5nsv rew
set path=($path /usr/local/ym)
rm -fr /var/tmp/cdrom
mkdir /var/tmp/cdrom
mkdsc_mo

Set MakeDisc Path... to /usr/local/ym/
Set Work Directory... to /usr/tmp/cdrom
Set Base Directory... to directory of data to go onto CD-ROM.
Set Output Device/File... to /dev/rmt/tps0d5nsv
Set Output Device/File Size... to 650 Mbytes (74 minute disc. 540 M for 63 min disc).
Set Output Block Size... to 16
Leave the offset and padding at zero.

From the Options menu, pull the Volume item. Fill in the blanks (formal disc name, formal disc set name, publisher name, formatting by, applications, copyright notice file, abstract file, bibliography file). No blanks permitted, use underscores. Click on creation date, click on ALL to set time to current time.

From the Options menu, pull the Flags item. (Left side): In order to get the original UNIX filenames, you must leave "Include Rock Ridge Extensions" checked (the default). This in turn means that you can't check "copy files" or "copy directories" -- so symlinks go on the CD "as-is". Check "Abort on Directory Depth Warnings", if you have more than 8 levels of subdirectories, fix your directory structure. (Right side): Check on "Record Translation Tables" to enable Original Name Recovery. Replace the "Map file" name which defaults to "YMTRANS.TAB" to be ".MAP", so that the map files are invisible for UNIX readers. Click on "OK".

From the Image menu, pull the Premaster item. A log window pops up. Now watch the guy hammering a CD out of the rock for a long time.

When the "Ready to dump CD-ROM image to output device" window pops up, this means that the directory maps have been built. Click on "OK". This will begin the process of loading the CD-ROM image onto the CD-Studio's internal hard drive.

To cut each copy to CD, load a new blank CD, wait for the green "disc in" light to come on steady. Note that it will blink for 10 seconds, stop blinking, then blink a few more times. Don't run any operations until it's on steady. Then run:

mt -f /dev/rmt/tps0d5nsv rew
mt -f /dev/rmt/tps0d5nsv rew
mt -f /dev/rmt/tps0d5nsv fsf
The red "HDD" light on the CD Studio should begin pulsing regularly, and amber "writing" light on the Philips recorder will come on steady. Assuming a full CD of data, the recording process takes 40 minutes.

It's easy to get faked out about when the process is complete. The HDD light will stop flashing, the amber "writing" light will go out. A few seconds later, the amber "writing" light will come back on solidly for 30 seconds. Then it will go out for 3 seconds, then it will come back on solidly for another 20 seconds. Do NOT press the open/close button until the amber "writing" light has gone out and remained out for 10 seconds.
