An invention disclosed includes a layer number obtaining section ( 222 ) for determining which information storage layer (L 1 ) has been accessed and a layer type identifying section ( 223 ) for identifying a type of the information storage layer (L 1 ) determined by the layer number obtaining section ( 222 ). With the configuration, even in a case where an information recording and reproducing apparatus accesses an information storage layer different from an intended information storage layer by false operation or the like, it is still possible to dissolve mismatching between a recording or reproduction control scheme being set up and a recording or reproduction control scheme suitable for the information storage layer thus accessed.

The invention relates to recording methods for recording information on a dual layer recordable disk, and to corresponding recording devices. In one such method and recording device the OPC-area is variably located on a layer of the disk. In a preferred embodiment the OPC-area is located relative close to the radius where the data stream switches from the first layer to the second layer. This reduced additional time required for jumping to a fixed OPC-area. Furthermore, in another such method and device the information to be recorded is equally divided over both layers of the dual layer disc. This avoids additional time required for finalization.

In an optical disk manufacturing apparatus, a movement mechanism changes the movement speed of a laser beam irradiation component from a first to a second speed at a first radial position located within where the laser beam irradiation component moves from an inner peripheral region of the optical disk to an identification information recording region of the optical disk, and changes the movement speed from the second to a third speed at a second radial position at which the laser beam irradiation component has reached the identification information recording region at the second speed. The second speed is lower than the first speed and the third speed. The laser beam irradiation component records the identification information by irradiating with a laser beam while alternating between a first power level and a second power level low enough not to crystallize the recording layer, when moving through the identification information recording region.

In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.

A method for backing up and restoring a disc management information is disclosed. Firstly, a specified optical disc is loaded into an optical disc drive. After a servo calibration process is performed, the latest update of the disc management information is read from a specified optical disc. If the latest update of the disc management information is read successfully, the optical disc drive enters a normal working state. If the latest update of the disc management information is not read successfully, the latest update of the disc management information is acquired through a processing circuit. Consequently, the optical disc drive enters the normal working state. While the normal working state of the optical disc drive is terminated, the latest update of the disc management information is transmitted to the processing circuit and recorded into the storage device.

재기록 가능한 광 기록매체 및 광 기록매체의 스페어 영역 할당 제한 방법에 관한 것으로서, 특히 내주 스페어 영역이 할당된 광 기록매체에 가변적인 크기의 외주 스페어 영역이 할당될 때마다 상기 외주 스페어 영역의 확장 횟수를 기록함으로써, 상기 외주 스페어 영역의 확장을 제한하는 것이다. 그리고 상기 외주 스페어 영역의 확장 횟수가 기록되므로 시스템이 확장된 상기 외주 스페어 영역의 사이즈를 용이하게 확인할 수 있고, 또한 상기 외주 스페어 영역의 확장이 제한되므로 스페어 영역이 무한정 확장되는 등의 문제가 없어져 시스템의 퍼포먼스를 높일 수 있다. The present invention relates to a rewritable optical recording medium and a method of limiting the spare area allocation of the optical recording medium. In particular, the number of expansion of the outer spare area is determined whenever an outer spare area having a variable size is allocated to the optical recording medium to which the inner spare area is allocated. By recording, the expansion of the outer spare area is limited. In addition, since the number of expansion of the outer spare area is recorded, the system can easily check the size of the outer spare area that is expanded, and since the expansion of the outer spare area is limited, there is no problem such that the spare area is infinitely expanded. Can increase performance.

The present invention relates to an optimal recording method of an optical recording medium in which optimal recording condition information for data recording is recorded on an optical recording medium and is used for subsequent data recording. A method of overwriting data on an optical recording medium in which recorded recording conditions are recorded in a predetermined area, the recording light having the largest value from the above recording conditions including information on the detected optimal recording optical power. A first step of checking power and a second step of performing a requested rewrite operation using the identified recording optical power, wherein the optimal recording condition information of the inserted optical recording medium is included in the count area of the optical recording medium. Alternatively, the recording operation is performed by additionally recording on the lead-in area to quickly determine the optimal recording optical power in the future data recording. In the data rewriting, data recording is performed by recording optical power larger than the previously recorded recording optical power, so that even if the data rewriting is performed, the optimal recording operation is achieved without degrading the reproduction characteristics of the recording data. It is a very useful invention.

Without drastically modifying the specifications of information recorded on a disc-shaped optical recording medium which has been processed conventionally by a dedicated player, the disc-shaped optical recording medium can limit reproduction by a disc drive belonging to a computer and prevent unauthorized copying. A deformed pit string containing a special wobble and shift of a pit string of an information track is provided as a read out limit area. In this read out limit area, during a low-speed rotation of the disc-shaped optical recording medium, follow-up is possible by optical pickup tracking control and it is possible to reproduce properly. However, during a high-speed rotation of the disc-shaped optical recording medium, it is impossible to perform follow-up by the optical pickup tracking control to perform reproduction.
