Abstract
A disk drive connectable to a host system includes a disk, a buffer memory, and an audiovisual interface responsive to first data from the host system to provide audiovisual data. The disk drive further includes a host command interface adapted to receive host commands from the host system. The disk drive further includes a disk controller coupled to the audiovisual interface, the host command interface, the disk, and the buffer memory. The disk controller is responsive to the host commands to selectively allocate at least a portion of the buffer memory among the audiovisual data, and to selectively transfer the audiovisual data from the audiovisual interface to the buffer memory. The disk controller is further responsive to the host commands to selectively transfer the audiovisual data from the buffer memory to the disk to be stored.
