Inside a Nexperia

vbimport

#1

I disassembled my DRU-810A. Every single part of it. I noted every text that there was on the parts. They may be useful, and cool too, to check the inside of the drive. Poor drive… I hope anyone can help me find out what do these words/numbers mean (what chip/what it does). If you do know, please reply.

Some pictures: (please ask if you want higher quality ones for a specific part of the drive)

Excellent work and very interesting, but I am wondering why you went though all this time comsuming work for a chipset that is dead and long gone? Please do not get me wrong cristyro, I love the Nexperia chipset and wish they could implement it in an SATA Optical drive but alas I do not think that will happen. I think all Optical drives with the exception of a few BD drives will be gone in a few years. But I have to commend you on a very interesting and informative post, I am going to make it a sticky so it stays around for a while, You sure put alot of work in this. Thank you.:bow:

Thanks, alan1476. I did this because the drive was destroyed anyway, I was just keeping it without any use so I decided to open it. Why trash it when I can have fun with it? I can learn from this info. Also, Nexperia is like a legend, it will never die for me. I think this may be true for a lot of real CDFreaks like us. That’s what we do: study media, drives, etc. And, why not? I haven’t lost anything while doing this. It was hard sometimes, because it was so hard to open I had to use “pliers” (I don’t know if the word is correct, sorry for my english if I’m wrong). Thanks for the reply anyway. (and wow, sticky? that’s awesome)
