CD-R and CD-RW blanks information


This page shows what types different brands of CD-R blanks really are, and how good some of them performed on my drives. The ATIP information is from CDR Media Code Identifier 1.45 to 1.52 and Cdrecord release 1.8a28 to 1.8.1. I have tested some of the discs with different CD drives. The old CD drive used for compatibility testing is a Sony CDU-31A 2x drive with proprietary interface from 1993. Of course I cannot test CD-RWs with it - it is far too old to be multiread-capable. Most of the compatibility problems can be solved by recording the CDs in DAO (Disc At Once) mode. Some of the discs were also tested in a "middle-aged" drive, a 1997 Toshiba XM-5702B, and in a friend's drive, a Samsung 32x max.

Comments:          After burning audio to the test disc, the ATIP was
                   unreadable. It took a long time to be recognized in the
                   recorder, and sometimes in not recognized at all. It works
                   perfectly in the other drives though.

                   seem to compute a rough laser position from the sector
                   number/time code, position the laser there and then find the
                   exact position by reading. The formula to find the rough
                   position is based on the spiral geometry of a 74 minute
                   disc. If it is used on a 90-minute disc, these positions are
                   wrong because the spiral is tighter. The laser is too far
                   out and the drive has problems finding the correct position.
                   With the outermost sectors, the rough position is outside
                   the range of the laser assembly. The Toshiba's laser sled,
                   for example, hits the outer limit with an audible clunk. In
                   a drive that is not as solid as the Toshiba, that might even
                   cause damage.
                   Audio players generally don't use the fast sector seek
                   technique. The 90-minute test disc played well in all audio
                   players I tested. The only CD-ROM drive that could read them
                   without trouble was the old Sony CDU31A. The Philips CDD4201
                   does not even recognize it.
                   Apart from the positioning problem, these discs are of very
                   good quality. They show no C2 errors.

Comments:          Do not burn a Ritek gold CD on a Philips 2x or 4x writer. That produces
                   discs that can be read only by a few drives. Even audio discs can click
                   and pop. If you use another writer, e.g. a TEAC CD-W54E, these blanks
                   make very good CDs that are fine with all readers.
