    why cant i read a gc disc on my pc - THE TRUTH

    ok guys this explains a whole lot of why you cant read a gc disc on your pc these are the patents used in the drives and discs on the gamecube, maybe someone can figure something out (like has anyone tried reading these discs on a dvd-RAM drive?)

    [Only registered and activated users can see links. ] is about the drive used :


    Title: US6009057: Disc drive equipped with identification indication reader provided in an optical disc

    Abstract: A disc drive is provided with an optical pick-up for reading data recorded in a program area of an optical disc; and a photo-interrupter for optically reading out bar information of a bar code which is arranged in an arc shape within at least a part of an annular bar code area provided on the optical disc between the program area and a clamping area of the optical disk so as to be readable from either side of the top and underside surfaces of the optical disk, wherein the photo-interrupter is located on the opposite side of the optical disc relative to the optical pick-up when the optical disc is loaded in the disc drive to read the information of the bar code from that position. Preferably, the photo-interrupter is provided on a clamper support which is provided for supporting a disc clamper for holding the optical disc between the disc clamper and a turntable for rotating the optical disc. This arrangement makes it easy to provide the photo-interrupter for reading the bar code.
    More details regarding the dual barcodes (the big printed one and the one on the disc surface) one is for the drive, the other is for the cube to identify the disc once the main one is read by the drive.

    Abstract: An optical-disk playback apparatus plays back an optical-disk on which control programs defining the operations of the optical-disk playback apparatus and other information are recorded. Such optical-disk playback apparatus is operable by a combination of an optical-disk, such as a laser disk or CD, and printed materials on which barcodes are printed. Predetermined programs are recorded defining the operation of the optical-disk playback apparatus corresponding to the barcodes. As a result, variable, complex and yet flexible optical-disk playback operations which are not fixed at the initial system designing stage can be accomplished by simply tracing the printed barcode. The operation of the optical-disk playback apparatus is controlled by the control programs recorded in the optical disk. Difficulties which might occur when an optical-disk and barcode of different systems are combined can be prevented since a one-to-one correspondence between the barcode and the optical disk code is established beforehand.

    i guess that could be our problem guys.

    Pretty sure the inside barcode is just used in the factory...

    As for the other 'barcode' (that you can see thru if you hold it up to the light) - I reckon it's just there to make regular DVD drives wig out, and the TOC is read by the cube from the small gap in it.

    Has anyone tried hot-swapping discs and then skipping to somewhere after the barcode but before 1.5gig, to see if there is anything readable at all (by anything other than a cube)?

    I don`t know if this is going to be of any help to anyone but ive read other posts saying that people can only read the first 44 bytes of the gc disk, im attaching this file which allows you to see the correct size of the disk this also allows for direct audio cd ripping , just put into your windows\system\iosubsys folder and reboot for changes to take effect.
