Title:
OPTICAL DISK UNIT AND RECORDING METHOD ONTO OPTICAL DISK
Document Type and Number:
Japanese Patent JP3724745
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk drive in which an audio CD-ROM, or an audio DVD, a CD-DA (compact disk digital audio), a CD-ROM, etc., are loadable and which automatically plays those disks by discriminating and checking the types of the disks.
SOLUTION: A CPU 14 discriminates the type of a disk from a signal read from a disk 1. An orthogonal transformation-Huffman code decoder 26 performs signal processing such as decoding processing, etc., that corresponds to required encoding at recording in accordance with the type, providing a playing mode optimum to the optical disk.
