[QUOTE=Arachne;2127466]I’d be interested in hearing about those, if you have the time to go through them :)[/QUOTE]
Here’s a couple to keep you occupied my PURRRRY friend. These were the first two that came to hand. I will try and dig out some more if I have time but this week I am supposed to be resting then packing before migrating south next week (I’ll be back in October).
The first disc is from April 1998. I am not sure how rare it is but I thought it worth deviating from the thread topic a bit and posting a scan (apologies to Pepst).
Unbranded - White label with black lettering.
“CD-R 74 multispeed disc”
“Recordable 74 minutes 650MB”
“No. 07 337”
There is also a Compact Disc Recordable logo and a barcode. No speed is given but at the time the fastest CD writers were 4x.
The disc has a gold reflective layer and nothing printed on the top. It is a Cyanine dye and if I remember correctly the last number of the ATIP code gives the exact type (type 0).
Manufacturer: : CMC Magnetics
MID : 97m26s60f
Capacity: : 75:00.00
The disc is perfectly readable and the transfer rate test is perfect (Samsung SH-S202N used). I also did a Benq scan which I think is very good for the age of the disc. There is a large E22 spike halfway which is due to a hole in the top of the disc (through reflective and dye layers). The upper surface of the disc is not very well protected and I think that the hole was caused by the corner of the jewel case lid. The disc has been written on in fine black marker but this does not appear to have done any harm.
The BLER is very low across the rest of the disc. If it wasn’t for that hole this disc would be right up there with my best Verbatim Pastel Taiyo Yuden. The BLER average for the first part of the disc before the hole was 0.14 with a maximum peak of about 16. An amazing result for a disc over 10 years old, and remember it’s a cheap unbranded disc (although back then cheap was about Â£7 per CDR disc). I wish that CMC Magnetics (or anyone else) made discs this good now.
The second disc is a Memorex 1-8x 80 Minute CDR “Professional Recordable Compact Disc”, part of a box of 10 (in jewel cases) I purchased in 2000 for Â£12. So again it is probably not very rare. The disc has a silver reflective layer, a Cyanine dye (type 1) and Memorex branding printed on the top.
Manufacturer: : Lead Data
MID : 97m26s51f
Capacity: : 79:59.74
It was written in September 2000 on a 4x Panasonic IDE drive (I can’t be bothered to look up the exact model). Like the previous disc it is still readable and the transfer rate test was perfect. I haven’t done a proper scan of this disc, but a quick scan showed that it has a much higher BLER average than the first disc.
After 8 years I am still using the cardboard box the Memorex discs came in to store CDs in sleeves.
