摘要： A method of reproducing data from an information storage medium having a plurality of recording layers, each layer having a user data area, on which data is recordable by a pickup. A first amount of data is reproduced from a recording layer located closest to the pickup and lesser amounts of data than the first amount of data are reproduced from other ones of the plurality of recording layers. The amount of data reproduced from each of the other ones of the plurality of recording layers progressively decreases from the recording layer closest to the pickup to a recording layer farthest from the pickup.

摘要： An information storage medium and a method and apparatus for recording/reproducing data on/from the information storage medium. The information storage medium includes a plurality of recording layers, each having a user data area, on which data can be recorded by a pickup. Data is recorded in the order of recording layers from closest to farthest from the pickup, and a recordable region in a user data area of a recording layer on which data is to be recorded is smaller than that in a recording layer between the pickup and the recording layer on which data is to be recorded. Each recording layer contains a recordable region in a user data area and a optimum power control (OPC) area in order to maintain the same recording/reproducing characteristics between the plurality of recording layers.

摘要： An information storage medium and a recording/reproducing apparatus and method are provided with the ability to extend at least one middle area of an information storage medium comprising two or more recording layers so as to ensure optimal data recording/reproduction. The information storage medium comprises a plurality of recording layers, each including a user data area for recording user data and at least one middle area used by a recording/reproducing apparatus that records/reproduces data on the information storage medium to move among two recording layers, wherein the at least one middle area is extended when the information storage medium is finalized. As a result, when an information storage medium that contains an OPC area for obtaining optimum recording conditions (such as recording power) in an outer circumference thereof is finalized, and if a middle area of the disk is not large enough, the middle area can flexibly be extended.
