摘要： A computer program product, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory signal per se. Moreover, the program instructions readable and/or executable by a controller to cause the controller to perform a method which includes: collecting, by the controller, data relating to operation of a tape drive; storing, by the controller, the collected data in wrap sections of a tape map; and storing, by the controller, a subset of the collected data in a slice region upon experiencing a first trigger condition and/or upon reaching a predefined location on a tape. Moreover, the wrap sections of the tape map correlate to physical lengths of tape. Other systems, methods, and computer program products are described in additional embodiments.

摘要： A disk device includes a recording medium having a plurality of recording surfaces, where each of the recording surfaces includes a system region for recording system data related to an operation of the disk device, and a controller configured to control recording of the system data in the system region. The controller is further configured to divide the system data to be recorded into a plurality of portions of divided data of the same size. The controller is further configured, after recording of a first portion of divided data in a first system region disposed on a first recording surface, to start recording a second portion of divided data in a second system region disposed on a second recording surface. The recording of the second portion of divided data is started after a switching time, during which switching from the first recording surface to the second recording surface transpires.

摘要： In a controller of a tape drive, when a command processing unit receives a Write FM0 command, a channel input/output unit writes the data in the buffer and a speculative FM onto the tape, and a CM input/output unit records speculative FM presence information in a cartridge memory. When the command processing unit receives Write FM1 command next, the CM input/output unit erases the speculative FM presence information from the cartridge memory. When the command processing unit receives a command other than Write FM1 command next, the channel input/output unit overwrites a speculative FM.

摘要： An optical recording medium having a read-only storage area and a writable storage area and a recording/reproducing apparatus and method therefor. The optical recording medium is a hybrid disc having both the read-only storage area, which is suitable for mass production of information having the same contents, and the writable storage area on which data can be recorded, updated or added at a user's option. The read-only storage area has a structure that is completely compatible with a digital versatile disc read only memory (DVD-ROM) specification, and the writable storage area is compatible with the recording/reproducing characteristics of a writable DVD specification so that an existing reproducing-only apparatus can read information from the read-only storage area, and data can be recorded in the writable storage area using an apparatus obtained by minimally changing an existing recording/reproducing apparatus while maintaining the physical recording characteristics of the existing recording/reproducing apparatus.

摘要： The invention relates to a record carrier of a disc-like optically inscribable type, having a preformed track in which an auxiliarily signal comprising a sequence of codes is recorded by means of a preformed track modulation. The codes comprise a sequence of address codes (AC) specifying the addresses of the track portions in which said address codes (AC) are recorded and special codes (SC). The special codes (SC) can be distinguished from said address codes (AC) and specify control data for controlling a recording by a recording device. The sequence can be obtained by replacing in a sequence of address codes (AC) with consecutive address values a plurality of said address by special codes (SC). The periodic pattern of address codes and special codes has a predetermined positional relationship with respect to a predetermined reference address. Such as for example a positional shift with respect to the start of a Lead-in area. The presence and or amount of such a shift may be used to represent additional control information or indicate the presence of area on a disc provided with such additional control information.

摘要： The invention provides a method for reading information of an optical data storage medium. First, one sector of the optical data storage medium is obtained. The sector is then decoded to check if the sector is reliable. When the sector is not reliable, a data rescue process referring to spec-defined or pre-defined information of the physical specification of the sector is performed in order to obtain disc fundamental information of the optical data storage medium.

摘要： When moving image data or the like is recorded into an information recording medium, such as a flash memory, in real time, an influence of locations of free recording areas upon the recording speed is suppressed to ensure the real time performance of the data recording. In an access apparatus, there is provided an area management block control part that manages FAT1 and FAT2, which are area management information of a nonvolatile memory, on a FAT block-by-FAT block basis, and the length of the free recording area in each FAT block is calculated. Then, area management block information, in which the free recording area length in each FAT block is recorded, is generated on a RAM. A FAT block in which the free recording area length exceeds a threshold value is assigned to the data recording, thereby suppressing the number of updates of the area management information regardless of the location of the free areas. In this way, the buffer overflow can be prevented from occurring due to a high frequency of the updating of the area management information, thereby ensuring the real time performance during the data recording.
