ATIP 97m24s01f (really TY)

“Manufactured by PHILIPS for Toshiba” ??



#1386

Today’s ultra rare media.

That’s CDR-63PY
Made in Japan by Taiyo Yuden Company Limited
ATIP = 97m 24s 01f
Silver reflective layer, cyanine dye

Taiyo Yuden produced 63-minute CD-Rs with a silver reflective layer for several years (circa. 1998-2000). As larger 80-minute CD-Rs became more popular, the 63-minute products were quietly discontinued and 74-minute production scaled down.

Today’s rare media.

TDK CD-R74PWS White Printable Surface
Made in Japan by TDK Corporation
ATIP = 97m 32s 00f
Silver reflective layer, cyanine dye

Here is a piece of Japanese domestic market TDK white printable media from around 1998.

Today’s ultra rare media.

Mitsui Gold unbranded matte surface CD-R63 1x-6x (1996)
Made in Japan by Mitsui Toatsu Chemicals Inc.
ATIP = 97m 54s 00f
Gold reflective layer, phthalocyanine dye

So finally I obtained a few pieces of Mitsui 63-minute CD-Rs. The price was high, but I needed to have some of these in my collection. The ATIP lead-in is strange in that the last digit is ‘0’ which signifies a “long strategy” dye but as most of us know, Mitsui uses phthalocyanine which is generally classified as a “short strategy” dye. I don’t think that many modern drives can write this media correctly.


#1389

Maybe some old CD-writers can handle it. I´m surprised the about “6x”, can´t believe that a 6x-writer exist 1996.


#1390

Of course, but not many modern drives would be able to write it properly. Strictly for collective purposes only.

A lot of CD-R media from 1996/7 were labelled as “6X”, so this is quite typical. I remember buying my first CD-RW drive in 1998, when 8X drives were already available.


#1391

I bought at middle of 2000 the 12x Plextor 1210A, maybe 1998 were some SCSI 8x available, IDE 8x maybe not?

My actual 24x DVD-writers are unusable with much newer media, even 32x and 48x SKC would be burned 16x only, 800/870MB-CD-Rs are mostly also unusable.

So I agree with that :wink:


#1392

My first writer was a PATA/IDE 4X, but 8X was already available in 1998.

24X/32X writers were generally not that great. They couldn’t handle the oldest low-speed media well, and they had problems with newer 40X/48X/52X media too. At least with the 40X/48X/52X, you could use common high-speed media knowing that it would generally work correctly, even though old 8X and lower media was generally unsupported.


#1393

I meant 24x DVD-writer :wink: . I guess there´s not so much space in the FW to support all the media the 52x CD-writers knew.

My most reliable CD-writers were my 12x Plextor and 16x Teac. But after had 52x CD-writers I don´t liked to used em anymore, especially for faster media

Today’s ultra rare media.

NEC PC-CDR-01

ATIP = 97m 24s 00f
Gold reflective layer, cyanine dye

Looks like NEC did very little to distinguish “their” product from the “That’s” products of the time…

#1398

Wow, impressive.
I don’t have the KODAK 1H7819 made in Ireland.


#1399

I have never seen this TDK CD-R.

Mine look like this:


#1400

Which MID does the industrial DVD have?


#1401

What does “XG” stand for?


#1402

XG stands for eXtended General MIDI.


#1403

TDK’s discs at that time had a similar cover compared to their VHS tapes.


#1404

Why did Pioneer stop manufacturing discs?
Which MIDs do they have?
