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.
摘要翻译：当可以成功访问装入磁带盒中的磁带盒（MIC）中的存储器时，检测存储在MIC中的MIC类型以判断磁带盒具有的数据格式。为此，盒式磁带适于在不检测形成在磁带盒中的识别孔的情况下识别数据格式或装载的磁带盒。因此，可以容易地适应数据格式的任何将来的扩展。

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： 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.
摘要翻译：本发明的磁带盒配备有能够容纳至少包括每个磁带盒唯一的识别信息的管理信息的存储器。容纳在盒式磁带中的磁带被写入具有与存储器存储的识别信息相同的内容的标识信息。当磁带盒被装载到磁带驱动器系统中时，系统获取存储器存储的识别信息和磁带存储的识别信息，以确定它们之间的匹配。如果检测到这两组识别信息之间的不匹配被解释为意味着磁带盒被篡改，并且相应地限制了对盒式磁带的读取和写入操作。这增强了对磁带机系统的欺诈性使用的安全性。

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： 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： 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 drive apparatus employing a tape cassette including a solid-state memory in a cassette half unit that accommodates a magnetic tape. When recording application data on the magnetic tape, the application data is written in an area of a preset size of the memory, beginning from a leading end of the application data. In this manner, it is assured that the management information located at the leading end of the application data can be stored in the memory. In reproducing the application data from the tape cassette, the management information stored in the memory is exploited to save time in accessing the management information recorded on the magnetic tape.
