摘要： First information is divided into equal-size information pieces. Serial numbers are assigned to the information pieces, respectively. An encryption key is generated from a base number and a variable number varying for each of the information pieces. The base number is common to an information range managed by one licence. The first information is encrypted on a block-by-block basis in response to the encryption key to get encryption-resultant information for every predetermined minimum information unit smaller than the sizes of the information pieces. The encryption-resultant information is recorded on a recording medium. A determination is made as to logical addresses of heads of portions of the recording medium which are loaded with portions of the encryption-resultant information corresponding to the respective information pieces. Second information representing a correspondence relation between the determined logical addresses and the assigned serial numbers is recorded on the recording medium.

摘要： A first rotational head of a first azimuth angle and a second rotational head of a second azimuth angle are arranged on a rotational drum rotated at a constant rotational speed. Also, input digital signals are processed in a signal recording system to form blocks of digital recording signals, a magnetic tape is moved by a tape driving unit according to an information signal generated in a control unit, and the blocks of digital recording signals and the information signal are recorded on the magnetic tape in a recording operation through the first and second heads alternately tracing the magnetic tape. In a reproducing operation, the signals are read through the first and second heads and are reproduced in a signal reproducing system. When the input digital signals are transmitted at a standard data rate, the magnetic tape is rotated at a first traveling speed in the recording and reproducing operations. When the input digital signals are transmitted at a second data rate equal to 1/N (N is a natural number) the standard data rate, the magnetic tape is rotated at a second traveling speed equal to 1/N the first traveling speed in the recording and reproducing operations. Therefore, the input digital signals can be recorded and reproduced regardless of the data rate of the signals.

摘要： In a digital information modulating apparatus, first information signal is separated every m bit or bits, and n bit or bits are added to the head of every m bit or bits to change every m bit or bits of the first information signal into every m+n bits of a second information signal, where "m" and "n" denote predetermined natural numbers. The second information is pre-coded into plural pre-coded information signals in accordance with combinations of the added n bit or bits. A determination is made as to whether or not predetermined sync information is present in the pre-coded information signals. A sync detection signal is generated which represents the result of the determination. One of the pre-coded information signals is selected as a modulation-resultant output signal in response to the sync detection signal.

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.
