Databook about SONY's KSS optical pick up series

[tiefbassuebertr]

Hallo everyone,
I search a long time a data sheet ore book collection from optical pick up's especially from Sony (widest type range).
Only from Samsung I have found complete datas online - see
CDP Traverse Deck Model CMS-B35BG6 (Samsung Laser-Unit SOH-AAV) Part-No CDM31279
http://www.haluyatech.com/down/sgnec...6-20040303.pdf
CDP Traverse Deck Model CMS-B33SG6 (Samsung Laser-Unit SOH-AAX)
http://www.haluyatech.com/down/sgnec/CMS-B33SG6(20030210).pdf
Please let me know more about such data books from all KSS types.
Thank you very much,
Best regards
Andreas Kirschner

I have found in this case this web address - new for me:

http://www.sony-shiroishi.co.jp/product/index.html

a SONY department of opto electronical decices resp. laser diodes
There certainly know more about the exactly title and the years of release from old SONY data books about optical pick up's (laser units) especially the types KSS-120C, KSS-121A, KSS-123A, KSS-122B, KSS-152A, KSS-211A, KSS-270A, KSS-271A, KSS-272A, KSS-273A, KSS-274A, KSS-273B, KSS-281A and KSS-280A

Unfortunately all information are in Japan language and no e-mail address is to find. Perhaps at one of the members Japan is homeland and can call there
Thank you very much for finding informations

I still want to have informations of such databooks.

In my experience, which goes back to the beginning of cd, it's usually NOT the actual laser diode that goes bad in Sony pickups(though the earlier ones would need power output adjustment after a few years), but mostly the photodiode array chips. This is particularly true, god knows why, with the ones used in the beautiful, linear motor transports(excluding the wonderful first gen CDP-302/520 type), e.g., the KSS151, 272, etc. I've only seen one or two 151's where the laser got too weak to tweak up to range, and none of the later ones. Always the PD array chips, except for a very few cases of the lens suspension getting physically too weak to allow the focus servo to function properly.

Interesting observation. But I think, the reason for this are different brands and different quality standarts of PDIC's (also called OPIC = optical integrated circuit). The Sony types KSS270-KSS271-KSS272-KSS280 uses Mitsubishi's "M52102". By KSS273-KSS274 are "M52104FP" inside. This informations are according the regarded service manuals, that not automaticly means, that this is in all cases.
By the datasheet about KSM-213CCM no PDIC type is mentioned. Perhaps it could be IS-1682 clone (by short life time) or IS-1682 original version from Sharp. But without datasheets from SONY this and much others remains unknown.

are there any news?

databooks and cover pics from it still highly appreciated

Perhaps this can help, its the same site but then in Englisch, which reads better than Japanese

Sony Global - Laser Diode

goodluck

Who from Japan's member can call there and ask for vintage KSS data books so as successor diodes in the same outline for the vintage types SLD104U and SLD104AU ??
If I a guy from Japan, I knew that after few phone calls.
