Title:
DEVICE, METHOD AND MEDIUM FOR OPTICAL RECORDING AND REPRODUCING
Document Type and Number:
Japanese Patent JP3861513
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain optimum light power using smaller number of OPC processings.
SOLUTION: In an optical recording and reproducing device, a laser diode 12 emits light beams to a CD-R3 to record or reproduce data. A detector 13 receives the reflected light beams from the CD-R3. An RF processing section 17 extracts ATIP included in reproduced signals. A control microcomputer 20 reads a manufacturer's name and the manufacturer's code of the CD-R from the information recorded in the ATIP as special information, reads the light power corresponding to the CD-R from a memory 21 and determines the power as the initial value of the OPC processings.
