摘要： An optical disc medium includes a system area and a data area following the system area. A plurality of sets of an extended record control data area, a bordered area, and a border are possibly set in the data area continuously from the system area, and a first set of the plurality of sets does not include the extended record control data area. A user data is recorded in each of the bordered areas. In each of the plurality of sets other than the first set, a record control data associated with the user data which is recorded in the bordered area of the set is recorded in the extended record control data area.

摘要： An optical disk that has a BCA, from which data can be reproduced even if the BCA has defects. The data format of the BCA comprises a plurality of sub-data units and coupling codes, each coupling two adjacent sub-data units. The sub-data units contain the same data. To reproduce the data, the sub-data units are checked for errors. The data recorded in any sub-data unit that has no errors is reproduced and output to a next stage circuit connected to the optical disk drive.

摘要： A recording method of an information recording medium includes: (a) storing management information; (b) reading out the management information; and (c) recording. The information recording medium has two recording layers. A first recording layer is placed nearer to a source of a laser and a recording direction thereof is from the inner side to the outer side of the information recording medium. A recording direction of a second recording layer is from the outer side to the inner side. In the (a) storing, management information indicating a recording status of the information recording medium is recorded in a management information area of the information recording medium. In (b) reading out, the management information is read out from the management information area. In (c) recording, recording processing is performed by skipping a part of an area based on the management information.

摘要： An optical disc medium includes a system area and a data area. The system area includes a recording operation test area to which a trial recording operation is carried out to determine an optimal record condition when data is recorded in the data area; a record control data area where data necessary to record user data on the data area is recorded; and a user data lead-in area necessary to reproduce the user data from the optical disc medium. Dummy data are recorded to a portion of the record control data area on a side of the user data lead-in area to prevent a track-out when the data area is accessed.

摘要： The present invention provides a technique for improving reliability of reading header information. The optical disk is composed of a recording track. The recording track includes a data recording region in which recording pits are formed for recording data, and a header region in which pre-pits are formed for recording header information identifying said data recording region. Said recording pits have a reflectance smaller than that of a space in which said recording pits are not formed. Said recording pits and said pre-pits are formed so that an amplitude (dynamic range) of a level of an optical signal reflected from said header regions is larger than that of an optical signal reflected from said data recording regions.
