I like to experiment and so some day I read this excellent site "The truth about offsets". And I thought that it must be possible to burn AUDIO as DATA.

There are so many rumours, that copying AUDIO CDs @ high speed would decrease the sound quality. This is pretty a good proof that this isn't true if you have good hardware.

Of course you can use 99 min CDs but because they use the lead-in sectors of the disc, errors can occur, too.

At least, with WinRAR you will know if something failed, because of its CRC check.

Some time ago, before I tried this audio-method, I were looking for a tool that allows me to record DATA as Mode2/XA (2336). With this you would have a filesystem, too, esay access, and still more space to store data. OK, decreased security again, but it is still safer than audio. Even the PSX uses it ...
