Inventor: ARAI TORU
IPC: G11B7/005
Filed: 2002-03-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical disk recording and reproducing device capable of preventing wrong acquisition of management area information of a medium.  <P>SOLUTION: A control section 3 moves an optical pickup section 1 to an area, writable by the Manufacturer, not in use on the standard, and on which final area information of medium management information is written, and reproduces data written thereon to acquire information about the number of final TRACKs and medium address information in which a PMA (Program Memory Area) is written. Even in the case that data of PMA information can be reproduced only up to the midway due to a defect of the medium or defective writing to the medium, the apparatus acquires the information about the number of final TRACKs and the medium address information in which the PMA is written before reading the PMA in advance so as to realize prevention of acquisition of wrong management information of the medium because repeating retrial of reading up to the final address can avoid stop of reading of the PMA without acquiring all the information of the PMA even when a reproduction error of the PMA takes place on the way of reading.  <P>COPYRIGHT: (C)2003,JPO
