Title:
RECORDING CONTROL DEVICE AND METHOD, DRIVE CONTROLLER AND DRIVE CONTROL METHOD, RECORDING MEDIUM, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2015/182393
Kind Code:
A1
Abstract:
The present invention relates to a recording control device and method, drive controller and drive control method, recording medium, and program for making it possible to more reliably read information. In the present invention, a management unit generates a DMS as management information for managing a user data area and spare area of an optical disk. Additionally, the management unit records the generated DMS to a DMA on a DS0 surface of the optical disk and also records the generated DMS to a DMA mirror on a DS1 surface of the optical disk. In this way, because the DMS serving as management information is recorded to different areas of the optical disk, even in a state in which it is not possible to read the DMS from one of the areas, it is possible to read the DMS from the other area. This invention can be applied to a recording and reproduction device.
