CD-ROM Transport

Hit this link right quick...

http://www.minidisc.org/digital_out.html

I take it this could be extrapalated to create a CD-ROM transport with coax out. Then you can just pick up a CD-ROM (or DVD-ROM/CD-RW, etc., for that matter) with "Play/Pause" and "Forward/Backward" buttons, etc. and voila! a *very cheap* (and assumably durable) tranport is born.

I mean, I'm looking at the back of one of my spare CD-ROM drives (I work in the IT industry) and there it is: "Digital Audio Out."

What do you guys think? Has any of you ever tried this?

Thanks,
Mark

It is compressed sounding and thin but it works.

Well, for the heck of it, I purchased the SHARP GP1F38T module for a whopping $12, and an ASUS CD-S520/A5 CD-ROM drive (with it's *new* SSDD II suspension and anti-vibration system) for a whopping $18.

Now I just need to get it all put together...

I'll report back...

This is what I thought was interested and made me think, "If it's designed to this at extremely high speeds, then think of how quiet it must be reading a regular old audio CDs.

So I got the optical transmitter, installed it and ran TOSlink out from it to my DAC (and then out to the amp)...

I got sound, but the speed is doubled, or trippled, or maybe even quadrupled - it's really fast. I've got some really slow-beat stuff, for example, that sounds like it's 300 bpm. Any idea why this would occur?

I guess CD ROMS are designed for speed in data reading (and going 2 directions) I would say the drive needs a controler that will set speed paramiters OR computers use buffers to keep info in memory and play it back at the proper speed.
