Optical data disc with multiple booting points

摘要

A booting procedure can take a long time and typically starts from a lead-in on a main data layer of an optical data disc. A Portable-Blue (PB) disc, a dual boot disc, includes a second data layer (304) from which application specific optical drives can boot directly. The dual boot disc still conforms to the prior art standard for PB for normal applications. The second boot (340) will cut in booting time for a specific application and will make application software small. is in particular relevant for gaming, for portable devices and relative specific applications.
