摘要： A technology is provided to improve tamper resistance in encrypting data to be secured and inputting/outputting the data between a recording device and a host device. When the recording device issues an input/output command to a storage device to input/output data to be secured, the recording device attaches an ID to the command to identify to which cryptographic input/output processing the command belongs. Upon reception of a sequence command, the storage device receives the command if its ID has been allocated and the command is verified to have been issued in the correct sequence. The sequence ID is used to identify a process system while appropriately managing the steps of executing commands.

摘要： A packet recording/reproducing system is provided which records or reproduces packets on or from tracks formed in time sequence on a magnetic tape. In a recording operation, the packet recording/reproducing system adds to input packets time stamps whose values are synchronous with packet arrival time control clocks produced by the system. The timing with which the packets are recorded on the magnetic tape is controlled by the arrival time control clocks so that a given number of the packets inputted at high data rate are recorded within a one-track area, a two-track area, or a one-track over area defined across at least two of the tracks, thereby minimizing the loss of capacity of the magnetic tape.

摘要： Digital signals are recorded in sequential tracks on a tape-form recording medium. In the case where the digital signals are recorded in accordance with a first recording format, at least first digital signals for normal reproduction are recorded in a single area of the first format on each track. In the case where the digital signals are recorded in accordance with at least a second recording format, at least the first digital signals are recorded in a specific area among divided areas of the second format, the divided areas being rewritable independently on each track, the specific area being common for both the first and second formats. And, second digital signals for special reproduction are recorded in previously determined areas among recording areas on each track, the recording areas being common for both the first and second formats.

摘要： A digital signal recording apparatus includes an amble generator for generating an amble signal representing a bit-sequence amble pattern. The bit-sequence amble patter can be detected and reproduced by a partial-response detection system “PR(1, 0, −1)” as a detected amble pattern having a period of state inversions which is shorter than a period of state inversions in a detected amble pattern corresponding to a recorded amble pattern of alternation of “1” and “0”. The amble signal generated by the amble generator and a first digital information signal are combined into a second digital information signal on a time sharing basis. The second digital information signal is recorded on a magnetic recording medium. For example, the bit-sequence amble pattern represented by the amble signal has repetition of six bits of “111000”.

摘要： In a recording and reproducing apparatus, time stamps are generated which represent moments of arrival of sequentially-inputted packets of data respectively. The generated time stamps are added to the sequentially-inputted packets respectively, and thereby the sequentially-inputted packets are converted into second packets respectively. The second packets are recorded on a recording medium. The second packets are sequentially reproduced from the recording medium. The time stamps in the respective reproduced second packets are detected. A detection is made as to whether each of the detected time stamps is correct or wrong. When a wrong time stamp is detected, a reproduced second packet is discarded which relates to the detected wrong time stamp.
