    摘要: An apparatus for accessing data from a disc with a linking area comprises a pick up head, a servo, a processing unit, a position predictor, and a control signal generator. The pick up head reads data from the disc and generates a read signal. The servo controls the pick up head. The processing unit processes the read signal and controls the servo according to a plurality of control signals. The position predictor tracks time position on the disc and generates position information. The control signal generator receives the position information and generates the control signals according to the position information.

    摘要: A recording/reproducing apparatus, for conducting edition works, such as, addition, movement, and deletion, etc., of data, onto a postscript type medium, defective management of which is conducted with using a replacement area, is disclosed. The apparatus includes a media information management unit. The medium management information is recorded by a renewal unit within a medium management information area. The apparatus further includes a replacement address information management unit. This is included within the medium management information. Furthermore, the apparatus includes an available number of times of edition works calculation unit. The available number of times of edition works calculation unit calculates the remaining available number of times of edition works, upon basis of remaining capacity of the medium management information area and renewal units thereof. Accordingly, display or notification of a correct available number of times of edition works to a user occurs.

    摘要: The present invention allows the usability of a write-once recording medium to be enhanced. The write-once recording medium is provided with an ordinary recording/reproduction area, an alternate area, a first alternate-address management information area (DMA) and a second alternate-address management information area (TDMA). In addition, written/unwritten state indication information (a space bitmap) is also recorded. The second alternate-address management information area is an area allowing alternate-address management information recorded therein to be renewed by adding alternate-address management information thereto. In addition, the written/unwritten state indication information indicates whether or not data has been recorded in each data unit (cluster) on the recording medium. Thus, it is possible to correctly execute management of defects and properly implement renewal of data in the write-once recording medium.

    摘要: A method of recording read/write compatibility information on an optical disc and a recording medium employing the method. Extended part version information, latest part version having recording capability, and latest part version having reproducing capability are stored in n.xy form on 6 bytes of a reserved zone of a physical format information zone of the optical disc. A recording/reproducing apparatus to record extended part version information on a reserved zone of a physical format information zone of a recording medium. The recording/reproducing apparatus has a base part version and a comparing unit to determine recording/reproducing compatibility with a recording medium having a detailed extended part version stored in a reserved zone of a physical format information zone.
