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.

Apparatus, method, and computer program for processing information

A recording media control apparatus is disclosed which includes: a host interface configured to connect recording media to a recording media unit, the recording media being subject to the writing and reading of data thereto and therefrom, the recording media unit incorporating an internal temperature sensor; an access request section configured to make either a data write request or a data read request to the recording media unit; a temperature status determination section configured to request temperature acquisition from the recording media unit in a predetermined cycle and, based on the acquired temperature, to determine temperature status of the recording media; and an access control section configured to transmit a command to the recording media unit via the host interface in response to an access request from the access request section and the temperature acquisition request from the temperature status determination section.

Recording media control apparatus, recording media controlling method, and computer program

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.

Recording apparatus, recording method, program for recording method, and storage medium that stores program for recording method

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.

Apparatus, method and computer program for processing information

An information processing apparatus may include plural media capable of recording data, and a control unit executing operation control of the plural media and at least one medium in the plural media may be a mechanical operation executing medium performing mechanical operations, and the control unit may decide whether the mechanical operation executing medium is selected as an access target, and when the medium is not selected as the access target, perform processing of setting the mechanical operation executing medium to a waiting state.

Information processing apparatus, imaging apparatus, information processing method and computer program

Disclosed herein is a data recording apparatus which may include a recording data acquisition section, a data recording section, a file management section, a recording control section, and a file updating control section.

Data recording apparatus, data recording method, and program

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.

Recording device, recording-medium-management method, program of recording-medium-management method, and recording medium recording program of recording-medium-management method

An information processing apparatus, an imaging apparatus, and an information processing method, and a computer program are provided. An information processing apparatus includes: an acceleration detecting part which detects an acceleration generated in the information processing apparatus; a storage part which stores history information based on information detected by the acceleration detecting part; and a control part which executes a determination process whether the information processing apparatus is in a falling state based on information detected by the acceleration detecting part and history information stored in the storage part.
