Method and system for accessing audiovisual data in a computer

A system for accessing audiovisual data in a computer, comprising:

• a hard disk, which is divided into a partition region and a non-partition region, wherein the partition region has an audiovisual table to record a location of the audiovisual data stored in the non-partition region and the audiovisual table is copied to a pre-determined location of the non-partition region, and the non-partition region is emulated as an emulated compact disk drive (CD-RW) drive for storing the audiovisual data;
• a hard disk controller, which has at least one command register to execute a hard disk access instruction;
• and
• a device driver, which sets a block size of the non-partition region to 2n-1 mega bytes and sets the at least one command register of the hard disk controller in accordance with an access instruction sent by the computer, such that the hard disk controller executes the hard disk access instruction, wherein n is a positive integer;
• and
• wherein the device driver performs a converting procedure to convert an access instruction to a compact disk drive into an access instruction to the non-partition region when determining that an access to the emulated rewritable compact disk drive is to be performed, and sets the at least one command register of the hard disk controller in accordance with the access instruction to the non-partition region and the audiovisual table, thereby accessing the non-partition region.
