Datasheet for Laser Pick-Up "HOP-A1" (or another o

[Kaiserich]

Hello,

because of my diploma-dissertation I´m searching the hole web for a datasheet for the Laser Pick-Up "HOP-A1" from Hitachi.
I need i.e. the pin-occupancy or input- and outputsignals.
Does anybody has such a datasheet or can tell me where I can find some?

I`d be much obliged when somebody could help me.

Or perhaps you have the datasheet of another Laser Pick-Up.
I would be happy to hear from you.

Thanks a lot for your effort

Martin
