摘要:
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.

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 may include a recording controller for controlling recording of management information containing access information corresponding to recording information for an information recording medium. The recording controller may record backup management information on a non-volatile recording medium prior to the recording of master management information on the information recording medium, and record the master management information after recording the backup management information. The recording controller may record a position information mapping table mapping a recording destination of the master management information to a recording destination of the backup management information in the recording of the backup management information.

A structure is provided that prevents damage to an HDD and loss of recorded data by prohibiting the hard disk from being shifted to the active state in a state in which there is a problem with an environment. On the basis of detection information of each of sensors such as a fall sensor and a temperature sensor, it is determined whether or not data recording or a playback process utilizing the hard disk can be executed safely. The hard disk is caused to be shifted from being in a suspended state to being in an active state on condition that it is determined that safe data recording or playback is possible, and a data recording and playback process utilizing the hard disk is executed. By using this structure, the hard disk is prevented from being shifted to being in the active state in a state in which there is a problem with the environment, for example, in the case of falling, the case of high temperature or high humidity, or the like, and damage to the HDD and loss of recorded data can be prevented.
