A communication system includes an initiator that transmits a command via an electromagnetic wave. The communication system also includes a target that transmits a response to the command by load-modulating the electromagnetic wave. The initiator performs a first mode communication to acquire real data. The response is transmitted by the target at a timing of any one of one or more time slots and includes the real data. The initiator has a unit that causes the command to be transmitted with a first value in time slot information when the first mode communication is performed. The target has a unit that recognizes the time slot information included in the command from the initiator. The target also has a unit that causes the response including the real data to be transmitted at a timing of a preset time slot, when the time slot information has the first value.

This invention provides a recording medium supportable device such as a library device (50), which authenticates each recording medium by identification information such as serial number and controls the recording medium by a command based on radio communication. In this case, a communication identifier like a session identifier corresponding to the identification number is set and provided and the communication identifier is included in a command at the time of execution of control, so that only a specified recording medium to be controlled carries out an operation corresponding to the command. When authenticating the recording medium, the identification information, which is proper information such as serial number, is confirmed through reliable communication using successive communication identifiers, and reliable authentication of the recording medium is carried out by several stages of communication.
摘要:
A tape cassette including a cartridge and one tape reel provided in the cartridge, with a recording medium in the form of a tape being wound upon the tape reel. In the tape cassette, a leader tape that is more rigid than the recording medium in the form of a tape is connected to an unwinding end of the recording medium in the form of a tape; a toothed portion (a protrusion) is formed on at least a portion of both side edges of the leader tape; the tape reel has a flange on a top portion and on a bottom portion of a hub, and feed teeth (engaging portions) that engage the protrusions of the leader tape are formed on outer peripheral edges of the flanges. Rotation of the tape reel in one direction causes the engaging portions to feed the protrusions, whereby the leader tape is sent out from the cartridge. The tape cartridge of the invention can be reliably mounted to a recording/reproducing apparatus.

A tape cartridge housing a magnetic tape includes an auxiliary storage medium having a storage unit in which to store the recording medium information such as design parameters or the number of times of recording and/or reproduction of the magnetic tape, and a transmission/reception unit for effecting inputting/outputting of the recording medium information with the recording and/or reproducing apparatus. The auxiliary storage medium is mounted so that the transmission/reception unit is exposed to the outside through an opening provided in a lateral surface of the main cartridge body unit not obstructing the loading of the magnetic tape, that is in a surface of the main cartridge body unit other than its front surface as an inserting end of the tape cartridge into the inside of the recording and/or reproducing apparatus. The auxiliary storage medium has an antenna constituting the transmission/reception unit for inputting/outputting the recording medium information with the recording and/or reproducing apparatus. It is through this antenna that the power is supplied from the auxiliary recording and/or reproducing unit provided on the recording and/or reproducing apparatus in accordance with a non-contact system transmitting the recording medium information and the power overlaid on the recording medium information.
摘要:
A tape driving apparatus and a recording medium, which is capable of reducing time in ejecting or replacing the recording medium and of maintaining accuracy, whereby is possible to load/unload a magnetic tape and to adequately manage it by setting a large number of partitions on the magnetic tape by storing management information in a memory within the recording medium. Then, it is possible to confirm whether or not the tape is adequately loaded by discriminating whether or not the tape is loaded correctly at the previous unloading position in loading the tape, so that the adequate recording/reproducing operation may be realized thereafter. Thereby, the time required for ejecting or replacing the recording medium may be remarkably shortened and the reliability of the driving operation with respect to the recording medium may be improved.
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:
When a magnetic tape cassette which may include a memory in cassette (MIC) device storing a system log therein is loaded, on the basis of a system log allocation flag read out from the magnetic tape it is judged which one of the magnetic tape and the MIC should be used as a location of the system log to be preferentially used by the tape drive device. If the system log to be preferentially used exists in the MIC, but it is impossible to read out the system log from the MIC, the system log allocation flag of the magnetic tape is rewritten so that the system log to be preferentially used exists on the magnetic tape, whereby the tape cassette is afterwards handled as a tape cassette with no MIC on the system.
摘要:
A recording/reproducing apparatus is provided in which an increase in recording density is achieved and in which the tape loading mechanism is simplified. A recording/reproducing apparatus of the type which uses a tape cassette which has a tape reel in a cartridge and in which a tape including a tape-shaped recording medium is wound around the tape reel, includes a take-up reel adapted to take up the tape-shaped recording medium and having a height equal to that of the tape reel of the tape cassette attached to the recording/reproducing apparatus, and a rotary head for recording and/or reproducing information on and/or from the tape-shaped recording medium by a helical scan system.
