the laser won't move off the disc of the little business card type of discs cuz they're basically just like tiny cds, but with extra material to make it have a rectangular shape. all of the disc's info is contained in the inner circular portion of the "card."
Yeah, but I was asking if it's possible to force the laser to move outside and try to read something. I guess Nero and other overburners use such feature, and I'd like to know how to program something similar in Windows, with two important differences:
1. I don't need to write stuff outside of the disk, I just want to read from there,
2. I want to do this with mini CD's, so there's no need to exceed the CD-ROM limits, like with ordinary CD's.
the capacity of a cd is a fixed value, just like any other storage medium. it's possible to overburn cds past their nominal capacity (650mb/700mb/etc), but not by a whole lot, usually about 2-2:30 extra.
Sure, and that's exactly what I'd like to obtain from the disk in my program, ie. if the disk has capacity of 650, 700, 200, 50MB. Note, that this is different from the outermost leadout reading, which changes when a disk is beeing closed.
as for technical links, the cdfreaks homepage has a lot of good information to start u off.
Unfortunately I can't find any CD-ROM programming reference here, and that is what I obviously need
