what about minidisc? Answered

does anyone have any clue as to how you could take minidisc components and somehow add them to a computer? i have an old sony portable MD player that i ripped apart and was curious as to why no one has tried this? there must be a way to do it because i thought i remembered there being an old Sony VAIO that had a built in minidisc drive on the fron of it. maybe i am mistaken, i dunno, but please let me know if there is any way of doing this! thanks!!


. Can you e-mail them to ? . I'll see what I can do with the model number.

. I got the pics. As far as I can tell, all you have is the transport. :(
. Unless someone else jumps in, I'd suggest heading for http://forums.minidisc.org/
. I'll leave the e-mail address open for a few weeks if you want to contact me.

. This looks like a good place to ask questions:
. Haven't found any free manuals, but if you don't mind spending a few bucks:

> internal ribbon type cables . I'm still lost. Can you post/e-mail a picture(s)? It sounds like I don't understand what parts you have to work with. . If all you have is the basic transport, this project is over my head. If you have the audio decoder circuits, I _might_ be able to help. . How about that model number?

model number MZ-E40 by Sony. i cant get my library to load so i can show the pic.

. Well, in theory, if you can hear it, you can get into the computer. . You can probably adapt a drive-bay mounting kit to work. If the MD player is a top-loader, you're gonna have problems mounting it in a computer so that you can insert/eject discs. . My Walkman MD recorder (MZ-R37) has an optical S/PDIF port that I use to dub from my CD changer. IIRC, the port is bi-directional. I've seen S/PDIF cards that should work. This will give you true digital. . It also has a "line out" jack that should work with just about any sound card. Very hi-fi, but probably not as good as S/PDIF. . You should be able to use the headphone jack with a sound card, but that may require some impedence-matching that is beyond me. . The manual should tell you what output options you have. You may be able to find the manual on Sony's web site.

aside from the obvious, i was trying to figure out if it could be wired into the computer just the same way any other optical drive could be. it has ribbon cables for the purpose of transporting data and power, so if someone knew how to get the schematics on any type of minidisc player, maybe its possible to rig it so you can use the minidisc the same way you would use a cd or dvd drive? thanks for the comment!

. If the ribbon cable is (E)IDE, it should be a snap. . Try Sony's web site. I don't think you'll find a schematic, but you may be able to ID protocols/power requirements/etc.

the thing about it is, the reason why i came here is because i am not smart enough to figure out how to do it on my own, so i am hoping with the help of the smart people here that it can be accomplished, lol! unfortunately, the ribbon cables i referred to on the minidisc device are not IDE type cables. they are the same type you will find in any other optical storage device. the ribbons are small and stiff and slide into a holder colored grey or brown.

. Tell you what, make an effort to find what you need on Sony's site (I think you're smart enough); if you're still lost, post the model number and I'll see what I can figure out. Deal?
. I don't mind helping you out, but this is a DIY site. ;)
. I don't understand your description of your cables. I can't remember seeing an optical drive that didn't use IDE. What am I missing?

sorry, i know i wasnt specific about the ribbon cables, i was talking about the internal ribbon type cables, not the external ones that are 40-80 pin. if someone could build the circuitry for an adapter that could go from the laser of the minidisc device and be converted to IDE, then maybe it could be tweaked to use the minidisc as a data device. let me know what you think and i will try to do the research for it.

. Cool! I don't use my MD much (seldom that far from a computer heehee) and haven't kept up with what's going on in the MD world. If someone had sold a reasonably-priced MD drive, I might have bought one. I'm hooked on CD/DVD now. . Are the HiMDs the same physical size as the "regular" MDs?

yes, physically they are exactly the same, only the capacity is different.

. Thanks. . BTW, if your unit has S/PDIF, and you decide to go that route, please let me know how it works out. Might do it to mine - have some live stuff I'd like to tranfer digitally.

I was after some measure of bytes. L

. Hmm. None of my discs are marked with a MB figure - just 74 or 80 min. . The music is stored compressed (don't remember the details) and I don't recall having seen MD used for data. No reason for consumer to be concerned with MBs. . If nobody comes up with an answer, I'll try to locate my manual and see what it says.

well i know that MDs use ATRAC compression when it comes to the music aspect, but i believe it is the equivelent of CD capacities. there are newer MDs that are called HiMD and they can be used for data as well as music but cannot be played in normal MD players or recorders, and they hold 1GB of storage.

sorry, they have the same capacities as CD's do, approx 650MB-700MB

What's the capacity of your minidisc? L

. BTW, if I understand what little bit I know about MD, you won't be able to use it for data storage.
