摘要： When a tape cassette is mounted, a tape drive apparatus judges whether the tape cassette is of a first mode (normal mode) or a second mode (multi-partition mode) based on one or both of management information that is read out from the magnetic tape and management information that is read out from a memory (MIC) incorporated in the tape cassette. The tape drive apparatus then an performs an operation setting in accordance with the mode thus judged.

摘要： A tape cassette of this invention is equipped with a memory capable of accommodating at least management information including identification information unique to each tape cassette. A magnetic tape housed in the tape cassette is written with identification information that is supposed to be the same in content as the memory-stored identification information. When the tape cassette is loaded into a tape drive system, the system acquires both the memory-stored identification information and the tape-stored identification information to determine a match therebetween. A mismatch between the two sets of identification information, if detected, is interpreted to mean that the tape cassette has been tampered with, and read and write operations on the cassette are restricted accordingly. This enhances security against fraudulent uses of the tape drive system.

摘要： A tape cassette of this invention is equipped with a memory capable of accommodating management information. Where the tape cassette is used, a MIC mode switch is written to a predetermined area on the magnetic tape held in the cassette. That item of information specifies whether or not the use of the management information held in the memory is mandatory upon write or read operations to or from the magnetic tape. A check is made on the consistency between the MIC mode switch read from the magnetic tape on the one hand and a result of access to the memory on the other hand. If an inconsistency is detected, that is interpreted as something fraudulent having been committed on the tape cassette. In such a case, read and write operations on the illegitimate cassette are restricted. This improves security of a tape drive system running the tape cassette.

摘要： A tape cassette of this invention is equipped with a memory capable of accommodating management information. The memory retains an MIC logical format type designating a format state, either formatted or unformatted, of the magnetic tape. A check is made on the consistency between the format state designated by the MIC logical format type and the format state estimated by reading data from the magnetic tape. If an inconsistency is detected, that is interpreted to mean that the tape cassette has been tampered with, and read and write operations on the cassette are controlled accordingly. This enhances security against fraudulent uses of a tape drive system loaded with the tape cassette.

摘要： When a memory in cassette (MIC) in a loaded tape cassette can successfully be accessed, an MIC type stored in the MIC is detected to judge a data format the tape cassette has. To this end, the tape cassette is adapted such that the data format or the loaded tape cassette can be identified without detecting an identification hole formed in the tape cassette. Thus, it is possible to easily accommodate any future extension of the data format.

摘要： A power conversion system includes n (n being an integer of 2 or more) power conversion devices (P1 to P4) connected in parallel to a load (4); and a communication line (2) connected to the n power conversion devices (P1 to P4). Each of power conversion devices includes a communication circuit (10) which transmits a load current value detected by a current sensor (37) to each of other (n−1) power conversion devices through the communication line (2), and receives (n−1) load current values transmitted through the communication line (2) from other (n−1) power conversion devices; and an operation circuit (11) calculating a shared current and a cross current of the corresponding power conversion device based on the n load current values. Accordingly, a wiring line is prevented from becoming complicated even when the number of power conversion devices is increased.

摘要： A solid-state imaging apparatus comprises a semiconductor substrate, a multiplicity of photo electric conversion elements, a vertical electric charge transfer device having a plurality of vertical electric charge transfer channels and transfer electrodes, reading out parts and a driving device that imposes a first voltage to the reading out electrode for reading out the accumulated signal electric charge from the photo electric conversion elements to the transfer channels in a reading out period and at a same time during the reading out period imposes a second voltage to at least one of the transfer electrodes adjoining to the reading out electrode for each photo electric conversion element for accumulating the signal electric charge in the vertical electric charge transfer channel under the one of the transfer electrode. Damage in the dynamic range of the solid-state imaging apparatus can be prevented.
