PMCD MASTERS MUST BE:
n E-32 error free
n BLER of 150 or less
n Accompanied by frame-accurate PQ Log sheet
n Disk-at-once mode
n Single Session
n 100% scratch free
n Backed-up by client
n Stored In A Standard Jewel Box
"Preferred" Mastering software is:
Digidesign / MasterList CD (MAC)
Adaptec JAM [Not Toast] (MAC)
Sony / Sonic Solutions (PC)

CD Architect and Steinberg Wavelab may work, but
I've encountered problems with both. I can't tell if the
problems are in the software, or caused by inexpeienced
engineers.  I can accept these, but they may be rejected
by my factory's Quality Control Department.

NOT ACCEPTABLE FOR MASTERS:
Adaptec Toast (3.x), 4.x DISK AT ONCE MODE IS OK
Easy CD Creator (PC)
Economy bundled software
CDRs created with Standalones (HHB/Marantz/Sony/Phillips/Roland)

"MIX MASTER" CDR Reference
Please don't confuse an audio "mix-master"  with a PMCD.
Your mix-master may be a final mix of good "audio quality",
but if it doesn't meet the above PMCD criteria, it has to be
recreated. If you don't know what you have, generally it
means you have a Reference. A PMCD must be created for
Factory Replication. If you don't want any changes in the
audio, I can "clone" your audio and create a Factory Spec
PMCD from your Reference. References without any scratched
can usually be used for short-run CDR copy jobs.

GDA is not responsible for any loss or damage to client
supplied Masters. Please do not send your only copy.
CDR Masters should be stored in a JEWEL BOX.

 
QUALITY CDR REFERENCES FOR SHORT-RUN CDR SHOULD BE:
n Created on a computer / Not a stand-alone recorder.
n Disk-at-once mode
n Free from scratches
n Good Audio Quality

Although I don't listen to client supplied disks, I'll do the
following tests before attempting to make copies:
1. Check the gaps for clicks or unusually long spacing
2. Listen to about 1-minute of audio at the beginning & end
3. Note the exact program length and number of sectors
4. Inspect the disk for scratches.
5. Determine the suitability of your CDR for replication.

Some stand-alone recorders do not make
acceptable References for copy jobs. They are:
HHB CDR 800
PHILLIPS "CONSUMER AUDIO" RECORDERS
ROLAND VS CDR RECORDERS

Some stand-alones can make suitable References for copy jobs;
the HHB CDR850/830, or the Marantz 600/610/620 or the new Sony.
Generally, all stand-alones don't do a very good job because of
the inaccuracy of the gaps. Computer written CDRs are preferred.

If there's any question about the suitability of client
supplied References, somtimes it's necessary to test one to
see if it works. This is for our mutual benefit as neither of us
wants to see you get copies which have problems. There
is a minimum $10 fee to test a disk, and if the program is long,
clients may have to listen to the test to verify it's OK. This
usually occurs when clients submit a scratched disk. The disk
may "play" OK, but audio playback versus reading the data from a
CD-ROM reader are entirely different matters. CD & CDR
technology incorporates error correction on playback. The player
machines "guesses" what the data should have been when it sees
a scratch, and then fills in the gap. Unfortunately, with a CD-ROM
reader (used in the copy process), that same scratch that "played"
OK is still a digital error and may come out as a CLICK on the copy !
