In an information recording apparatus, when it is determined to perform a copy process, a copy processor copies content data cached in a first storage section to an information recording medium as copy destination. A process-result sender sends, to a copy-count management server, a result of the copy process. A cached-data abandoning unit abandons the content data cached in the first storage section if information regarding an allowable number of copies on which the result of the copy process has been reflected represents that a next copy process is disallowed.

Information recording apparatus and copy management program for caching content data of digital content

An information recording apparatus includes: a transferring device that separately and simultaneously receives at least two information supplied through at least two channels, and separately and simultaneously transfers the at least two information to a storing device at separate transfer rates, thereby storing the at least two information into the storing device; a recording device that alternately reads the at least two information from the storing device, and alternately records the at least two information read from the storing device onto a recording medium at a constant recording rate; and a transfer rate setting device that sets the respective transfer rates to make a total of the transfer rates smaller than the recording rate.

Information recording apparatus with memory control structure

An information processor including a processing device for recording information on a recording medium or reproducing the information recorded on the recording medium, is provided with: an encrypting/decrypting device which is capable of an encrypting operation for encrypting the information to be recorded when the information is recorded on the recording medium and a decrypting operation for decrypting the information to be reproduced from the recording medium when the information is reproduced from the recording medium; the processing device which includes the two or more encrypting/decrypting devices; a control device which controls the encrypting/decrypting device so as to perform one of the encrypting operation and the decrypting operation; and a switching device which switches a transmission path of the information to the encrypting/decrypting device in response to one of the operations performed by the encrypting/decrypting device.

Information processor and information processing method

Linking gap detecting device and method in which a light beam is irradiated to an information recording track of an optical recording medium; a light detecting signal is generated by receiving reflected light of the light beam irradiated to the information recording track; a synchronous signal is detected from the light detecting signal; it is judged whether the existing interval of the synchronous signal lies outside a predetermined interval range or not; and the linking gap is detected on the basis of a result of the judgment.

Information recording apparatus

A desired catch-up time at which reproduction started after a start of recording of input information catches up the recording is set. Recording start time, present time and recording end time are detected. A rate of the reproduction necessary to catch up the recording at the set catch-up time is determined recording start time, present time, and recording end time. The recorded information is reproduced at a determined rate until the set catch-up time.

Information recording and reproducing system

An arbitrary desired reproducing time is set for reproducing information recorded on a recording medium, and an ordinary reproducing time is obtained based on management information recorded on the recording medium when the recorded information is reproduced at a standard reproducing speed. A skipping rate is calculated from the desired reproducing time and the ordinary reproducing time. A reproducing device is provided for reproducing the information recorded on the recording medium in the set desired reproducing time at the calculated skipping rate.
