ABSTRACT:
A method and system for accessing audiovisual data in a computer, which has a hard disk, a hard disk controller and a device driver. The hard disk is divided into a partition region and a non-partition region. The partition region has an audiovisual table to record a location of the audiovisual data stored in the non-partition region. The non-partition region is emulated as an emulated compact disk drive. When the device driver determines to access the emulated compact disk drive, it performs a converting procedure to convert an access instruction to the compact disk drive into an access instruction to the non-partition region, and sets a command register of the hard disk controller in accordance with the instruction converted and the audiovisual table, thereby accessing the non-partition region.
