摘要： Medium recording and reproduction apparatus and method can prevent prohibition of disc recording due to the fact that laser power calibration area becomes unusable by studying a management information update method during data recording. When usable capacity of the laser power calibration area is monitored and the capacity is reduced, management information area to be currently updated is changed to another layer.

摘要： When data is to be written on an optical disc in the unit of a sector, an attempt is made to read a block A to which a write sector belongs for the purpose of judging whether the block can be normally read. If the block A is not successfully read, it is judged to be a defective area, and an alternative write is performed in an alternative area in the unit of a sector. The alternative write may be performed so that a plurality of sectors belonging to the same block are dispersively written in different blocks d, E. When new data is to be written in a new sector in such a situation, data is acquired from the dispersed other sectors, merged with the new data, and collectively rewritten in the same block E.

摘要： A recording method and a recording apparatus capable of optimally arranging data on a write-once type optical disc. In a write-once type optical disc recording method with respect to a disc having a read-in, a user area, and a read-out by employing defect management information, the user area is divided into 3, or more pieces of R-zones; at least 2 recordable R-zones having recordable areas are present. When an unrecordable R-zone having no recordable area is present on the read-in side rather than two, or more pieces of the R-zones among the R-zones having the recordable areas, a linear replacement destination of a logical overwriting is determined to such an R-zone other than an R-zone having a recordable area, which is located adjacent to the unrecordable R-zone.

摘要： A data reproducing method for reproducing data, upon an optical disk of rewritable type, having an alternated block management area, a data area, on which recording/reproducing of the information is conducted by a unit of block, and an alternation area, on which recording/reproducing of information including a defective sector therein is conducted by the unit of block, through an information recording/reproducing apparatus enabling to execute Read Modify Write operation thereon, comprising the following steps of, in case where said alternation areas are in a plural number thereof when executing Read Modify Write operation onto said optical disk of rewritable type: executing reproducing on said data area including the defective sector therein, by only one (1) time; executing reproducing on said alternation area, thereafter, so as to hold data reproduced; and thereby reproducing the data. With this, it is possible to increase speed (i.e., speedup) in the reproducing time thereof, in total, but without necessary of reproducing operation upon the data area by a plural number of times.

摘要： The object of the present invention is to curtail the time required from the receipt of a demand for certification processing of a rewritable optical disk from an apparatus of the higher order to the receipt of a demand for recording processing. In order to achieve this object, a digital data recording method for recording on a rewritable optical disk includes certification processing including a first step of recording certification data for the certification processing on the optical disk, a second step of recording user data different from the certification data on the optical disk after the first step, and a third step of reproducing the data recorded in the first step or the second step after the second step, and switches the certification processing based on the result reproduced in the third step.

摘要： Provided is a technology in which a controller for controlling read/write performed to/from an optical disc includes a processor for controlling an interface, a temporary memory unit, a rotation control unit, and an optical control unit. The controller causes the processor to shift to a hibernate state when a predetermined condition is satisfied, and causes the processor to recover from the hibernate state into an active state when the interface receives a first command. The processor receives the first command from the interface, instructs the rotation control unit to drive the optical disc at a predetermined target rotational speed, instructs the optical control unit to perform a processing specified by the first command, transmits a completion notification of the first command to the interface with a delay, receives a second command after transmitting the completion notification of the first command, and executes the processing of the second command.
