No I agree there might be differences with slot loading and clamshell mechanics. But since the disk is sealed except for the bottom center and the bottom disc area, the rest isn't touched. They converted a xbox 360 drive to slot loading and they had to worry about the top and the bottom of the disc drive. MD only reads and touches the bottom of the disc, so even though its smaller it might be do-able. I would be most worried about if the Hi-MD laser/mag assemply travels farther or shorter then a regular md drive. I would love a slot loading 1 gb disc drive for my laptop or pc, I am going to try getting a donor slot md drive like an old sony or sharp 722 and a doner HI-MD drive. I was thinking the Sony MZ-NH600D would be a good drive, only 70-120 dollars and its HI-MD with usb connection. Any one have any opinion on any other cheap HI-MD drives to take apart. I want function and cheapness, looks don't matter.
