摘要： A standard reproduction model for ensuring real time reproducing on a disk-shaped information recording medium, includes a pickup (102) that reads the real time data from the information recording medium, a buffer memory (103) that temporarily stores the real time data read by the pickup, and a decoding module (104) that reads the real time data from the buffer memory (103) and processes the read real time data. An access time Tacc of the standard reproduction model is expressed by the following formula, Tacc=A·dN+Trev+B where dN is a difference in rotational speed of the disk-shaped information recording medium, Trev is a rotation waiting time at a target access position, A and B are constants.

摘要： The control device (610) controls the recording of data onto an information recording medium where the number of re-writing data onto the same area is limited. The control device (610) determines whether data to be recorded is real-time data or non-real-time data (S1). When it is determined that the data to be recorded is real-time data, the real-time data is recorded in a circular manner onto a second area which is defined in advance within a first area which is assigned in advance on the information recording medium (S2 to S5). When it is determined that the data to be recorded is non-real-time data, the search for an unassigned area is performed from a predetermined address within the first area. The non-real-time data is recorded onto the unassigned area found as a result of the search (S6 and S7). The search for the unassigned area for recording the non-real-time data is also performed in the second area within the first area (S6).

摘要： A simultaneous recording and reproduction method for recording a first real time data in an information recording medium while reproducing a second real time data recorded in the information recording medium, including the steps of: searching for unallocated areas on the information recording medium and allocating at least one unallocated area, each having a size which is greater than or equal to a minimum size Y, as an area in which the first real time data is to be recorded: selecting at least one area in which each area includes a non-used area having a size which is less than or equal to K from among the allocated at least one area, wherein K denotes the size of non-used area which is allowed within a window having the same size as the minimum size Y: recording the first real time data in the selected at least one area; and reading the second real time data from at least one area in which the second real time data has been recorded, whereby each of the at least one area has a size which is greater than equal to the minimum size Y, wherein the minimum size Y is determined to enable the simultaneous recording and reproduction, even if the non-used area having a size of K exists in each of two adjacent areas where data is to be recorded during the recording operations immediately before and immediately after an access operation, or even if the non-used area having a size of K exists in each of two adjacent areas where data is to be read during the reproduction operations immediately before and immediately after an access operation.

摘要： Congested rewriting in the same area is to be evaded to suppress the tendency towards occurrence of defective areas. When a stream 1 has been recorded, the last written address, representing the last written position, is stored. When recording a stream 2 next, recording is started directly following the position indicated by the last written address for the stream 1. The last written address, corresponding to the last address of the recording position, is stored. If the stream 2 is erased for recording a stream 3, recording is started not at a position directly following the last written address of the stream 1, but from a position directly following the last written address of the stream 2. When the stream 3 has reached the end of a recording area, the next following data is recorded as from a position directly following the stream 1.

摘要： A file system which is enabled to use a Metadata Partition instead of VAT for write-once discs, is provided by a pseudo-overwrite method. On applying this invention to a drive apparatus which supports pseudo-overwrite media, the file system distinguishes data to overwrite from data to append. When the data is newly written to a logical sector (S1305), the drive apparatus writes the data to a physical sector to which the logical sector corresponds (S1311). When the logical sector is overwritten the data is written to another unrecorded physical sector in the volume space (1321), and remapping information that specifies the original address, and the remapping address are stored in the remapping table (S1322).

摘要： An optical disk storing write-once information usable for protecting the copyright of the software by preventing the duplication, unauthorized use, etc., of the software. In the optical disk, a recording layer (213) is formed on a disk substrate (211) with a dielectric layer (212) inbetween. Then, an intermediate dielectric layer (214) and a reflecting layer (215) are successively laminated upon the recording layer (213), and an overcoat layer (216) is formed on the surface of the reflecting layer (215). A plurality of BCA (one of write-once identification information systems) sections (220a and 220b) are recorded by lowering the vertical magnetic anisotropy of the recording layer (213). At the time of reproduction, the write-once information is detected from differential signals.
