OPTICAL INFORMATION RECORDING MEDIUM, AND ITS RECORDING/REPRODUCING METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To reproduce an organic dye optical disk without any failure of focusing/tracking control even when it is inserted into an optical disk drive. <P>SOLUTION: This method includes: a step of making a converged laser beam access the identifier 108 of a control data area 104; a step of determining the identifier 108 to determine whether user data have been recorded; a step of making the converged laser beam access a user data area 106 only when it is determined by the identifier 108 that the user data have been recorded; and a step of reproducing the user data. <P>COPYRIGHT: (C)2007,JPO&INPIT |
