A filer of an information processing device continuously copies plural files recorded on a hard disk drive on an optical disc of an optical disk drive. An optical disc file system driver regards storing in a buffer of the file to be recorded on the optical disc as recording on the optical disc of the file and generates virtual management information for the file. In addition, the optical disc file system driver performs burst recording on a recording medium of a predetermined amount of data for each time when the predetermined amount of data of the file is stored in a buffer. Further, the optical disc file system driver updates the virtual management information by using information including a recording position of the file in the optical disc and records the virtual management information on the optical disc after completion of recording of the file on the optical disc.

Information processing device and information processing method for writing plurality of files on recording medium

In an information processing device, a control unitthat performs a job of storing information on a recording medium selected from among a plurality of recording media or a job of reading the information from a recording medium on which desired information is stored among the plurality of recording media by controlling a recording media drive is arranged. The control unitdivides a plurality of the jobs into a group performing storage of the information and a group performing reading of the information and performs a setting process of setting an execution sequence of the jobs in order of the groups and, for the job of reading the information, performs a combination process combining jobs of which recording media of transmission sources or transmission destinations of the information are common. Since jobs are executed in order for each group, and, in the group reading information, jobs of which recording media of transmission sources or transmission destinations of information are common are combined, the number of times of replacing a recording medium can be decreased, and accordingly, archiving and retrieval can be efficiently performed.

Information processing device and information processing method for controlled execution of storing and reading operations

An information processing apparatus includes a search unit, a selection unit, and a mounting processor. The search unit is configured to search for a plurality of roll back points of a file system. The selection unit is configured to select, from the plurality of roll back points searched for by the search unit, a roll back point corresponding to an operation made by a user. The mounting processor is configured to mount the file system at the roll back point selected by the selection unit to a read-only state, and further mount the file system to a readable and writable state according to an operation made by the user.

Information processing apparatus, information processing method, and program

Disclosed herein is a recording apparatus for recording a file stream which may be composed of a header, a body, and a footer onto a storage medium. The apparatus may includes header area securing means for, before recording of the body, securing in a recording area of the storage medium a header area in which the header is to be recorded; recording means for recording the body and the footer in the recording area of the storage medium, re-securing the header area secured by the header area securing means based on areas in which the body and the footer have been recorded, and recording the header in the re-secured header area; and reflecting means for allowing information concerning the header area secured when a recording process performed by the recording means is terminated normally or abnormally to be reflected in a file system of the storage medium.

Recording apparatus and method, program, and storage medium

Disclosed herein is a medium drive apparatus connected to an information processing apparatus for performing recording and reproduction on and from a recording medium in accordance with a request from the information processing apparatus, which may include an inputting and outputting section configured to record and reproduce data on and from a recording medium, and a control section configured to execute a first operation process as a reproduction only mode, a second operation process as a recording and reproduction mode, an authentication process with the information processing apparatus, and a mode changing process of changing the operation mode from the reproduction only mode to the recording and reproduction mode in response to success in the authentication by the authentication process thereby to control the recording operation and the reproduction operation of the inputting and outputting section.

Medium drive apparatus, operation method for medium drive apparatus, information processing apparatus, recording and reproduction accessing method for information processing apparatus, program, and program recording medium

An information processing apparatus adapted to be connected for use to a media drive apparatus for recording data on or reproduced data from a recording medium having a file system includes a real file system acquiring section that acquires the file system of the recording medium from the media drive apparatus and a virtual file system providing section that converts the file system acquired by the file system acquiring section into a virtual file system having a directory/file structure different from the directory/file structure on the recording medium and provides it to an application program.
