摘要:
The present invention relates to an information processing apparatus and method, a program recording medium, and a program which mitigate inconveniences due to a difference in recording format when performing the processing of copying or moving data between two recording media of different recording formats. A device control section 16 supplies UDF data, which is adopted for a DVD, to a device control section 17 together with an ATAPI command used when recording data onto a DVD. The device control section 17 converts the ATAPI command supplied from the device control section 16 into an ATA command corresponding to the ATAPI command, supplies it to an HDD 18 together with data supplied from the device control section 16 together with the ATAPI command, thereby controlling recording of the UDF data onto a hard disk 18A. The present invention is applicable to, for example, a hard disk recorder.

Information processing equipment is so constructed that the power consumption of a disk drive for hard disks, optical disks, or the like can be reliably and sufficiently reduced. The host CPU (120) of an information processing unit (100) forms a command for changing the power consumption mode of a HDD (200) based on the state of control on the HDD (200). The host CPU supplies the command to the HDD (200) through a media controller (106). When the HDD (200) accepts the command, it changes its power consumption mode according to the instruction from the information processing unit. Thus, the information processing unit can control the power consumption mode of the HDD (200) based on the state of control on the HDD (200).
摘要:
A recording device which records data onto a recording medium includes a nonvolatile memory storing and holding data on a free capacity of the recording medium, and a control unit controlling the data recording. The control unit determines the free-capacity data stored in the nonvolatile memory based on the total capacity of the recording medium when power is turned on. When the determination result indicates that a value of the free-capacity data stored in the nonvolatile memory does not exceed a value of the total capacity of the recording medium, the control unit records the data onto the recording medium with reference to the free-capacity data. When the power is turned off, the control unit updates the free-capacity data so as to reduce the value of the free-capacity data by as much as an amount of the data recorded onto the recording medium.

摘要:
A recording apparatus includes: a type detecting section that detects a type of storage medium; an erase-block size detecting section that detects an erase-block size of the storage medium; a recording section that records desired data to a data area in the storage medium and records management information of the data area to a management area in the storage medium; and a control section that controls the recording section by issuing a command to the recording section, on the basis of results of the detection. Each time a certain amount of data is recorded to the data area, the control section updates the management information in accordance with the recording, and when the storage medium is a storage medium in which recorded data is updated for each erase-block size, the control section increases the certain amount of data according to an increase in the erase-block size.

An information processing apparatus for recording data onto a recording medium, includes an access controller for outputting, to a medium-specific controller, record data input from an application and directed to the recording medium. The access controller performs a read-modify-write (RMW) operation by verifying whether one of a record start position and a record end position of the record data input by a logical sector unit from the application is different from a delimitation position of a physical sector as an access unit of the recording medium, acquiring the record data by the physical sector unit and storing the record data onto a memory if one of the record start position and the record end position is different from the delimitation position, updating logical sector data as part of stored physical sector data with the input record data, and outputting the updated physical sector data to the medium-specific controller.
