Abstract

PURPOSE:To record accurate information within a short period by including an unrecorded part, an ID part for recording an ID indicating the sector and address of the unrecorded part and a defect information part for recording defect information indicating the position and size of a defect in the unrecorded part. CONSTITUTION:The information recording carrier 1 includes the unrecorded art 2, the ID part 3 for recording the ID indicating the sector and address of the unrecorded part 2 and the defect information part 4 indicating the position and size of a pinhole or a flaw existing in the unrecorded part 2. The unrecorded part 2 is constituted as a land part 6 held between pregroups 5. The ID part 3 is constituted as plural prepit strings 7 arranged in each circumference of the land 6. The defect information part 4 is constituted as a defective data prepit string 9 arranged in the land 6 of the inner peripheral part of the carrier 1. The pit string 9 indicates the position and size of a defect exceeding the prescribed size and existing in the unrecorded part 2.

When recording information in the unrecorded area 2 at an arbitrary address, the sector and address data is read from the change in the amount of reflected light from the glybit array 7 by irradiating a focused laser beam along the pre-group 5, and then the information is recorded at an arbitrary address. Information is recorded by irradiating the land 6 at the address K with a modulated laser beam to form a signal bit 8. In this case, since defects 10 such as minute pinholes or scratches are scattered in the unrecorded area 2, the signal bits 8 and 8 are trapped.
Since there is a possibility that the information cannot be recorded correctly due to the inability to form the information correctly, the information is reproduced to check whether the information has been recorded correctly or not. Record the information again.

However, the above-mentioned conventional information recording carrier is configured to include an unrecorded part for recording information and an ID part to record an ID indicating the sector and address of the unrecorded part. On the other hand, since the unrecorded area is generally littered with defects such as minute pinholes or scratches, there is a risk that the user may not be able to record information correctly at an arbitrary address. It is necessary to reproduce and check whether the information has been recorded correctly, and if it has not been recorded correctly, to record the information again in the unrecorded area of a separate address. [Means for solving the problem] The information recording carrier of the present invention has a drawback that it takes a lot of time to record information on the recording carrier. , an ID section for recording an ID indicating the sector and address of the unrecorded section, and a defect information section for recording defect information indicating the position and size of the defect existing in the unrecorded section.
