CD PREMASTERING
CD Premastering/Recording
This procedure can only be performed by designated accounts with specific
privelages and quotas. The tools are set up by running
DISK$USER:[PREMASTERCD]LOGIN.COM
The first step is to copy the data to a source directory, which for the
Sky Survey CD-R's will take the form :
DISK$LOGICAL:[USA_AURA_STSI_SSSS_NNNN]
where SSSS is the designated survey identifier and
NNNN is the current CD volume number.
Valid Surveys are :
- DSS1 - Original 1st epoch surveys (already published)
- DSSH - High compression version of DSS1
- XDSS - Experimental 2nd epoch surveys
- DQVS - "Quick-V" survey
Remember to
update the index file for XDSS discs.
The premastering is performed with one of the commands MXDSS,
MDQVS or MDSSH as appropriate. After responding to several queries
regarding the source tree, the target image file and the volume names,
this will check the files, build a command file for premastering and
optionally submit it to PREMASTERBATCH.
Once the CD image has been created it is loaded to the internal hard-drive
of the CD-Studio recorder with the command YLOAD . This will
overwrite the existing image so be sure that it is no longer needed.
Place a CD-Recordable blank into the drive and initiate the burn
with the command YWRITE . This is a double speed drive so will
take about 30-35 minutes for a typical CD-R.
You may burn as many copies as required as long as the image
remains on the CD-Studio internal drive.
