摘要： PROBLEM TO BE SOLVED: To read cassette identification information when memory information cannot be accessed and identify a cassette by recording to a tape, information recorded to a memory loaded to a tape cassette at the formatting of the tape cassette as the cassette identification information. SOLUTION: When a tape cassette loading a memory is inserted, a tape recording/reproducing apparatus accesses information recorded to the loaded memory, extracts cassette identification information composed of mechanical electric characteristics, a format system of a tape and the like from the information, and records to a fixed area of the tape itself in a fixed mode. If the apparatus cannot access the memory information, the apparatus searches for a system area of the tape in a least significant mode of an AIT format. When detecting the system area, the apparatus tries to read starting from a most significant mode of the AIT format sequentially to a less significant mode, and sets an optimum process mode, based on the read cassette identification information.

摘要： PROBLEM TO BE SOLVED: To perform operation setting according to a mode automatically by discriminating modes being set to a tape from either or both of control information being read from a memory being provided at a tape cassette and control information being read from the magnetic tape. SOLUTION: A tape streamer drive for recording on a magnetic tape 3 by helical scanning is provided with a multi-partition mode for using the magnetic tape in three partitions or more. A tape cassette mounts an MIC:4 that is a non-volatile memory and stores control information including a history for each partition. When the tape cassette is loaded, a system controller 15 accesses the MIC:4. Then, when the control information is read appropriately, the tape cassette is recognized as a cassette in multi-partition mode and the mode information of a work memory 24 is updated to a corresponding mode. When the MIC:4 cannot be recognized, the magnetic tape 3 is run and the control information is read.

摘要： PROBLEM TO BE SOLVED: To provide a drive method for a tape streamer which allows the exact DRAW (write once after write) of fresh information to a magnetic tape without disappearance of recording information. SOLUTION: When an application data identification symbol of a recording system of a data file registered in a cassette memory of a mounted cassette tape is read out and detected and a '0≈ is detected as the application data identification symbol, the mounted tape is decided to be a standard tape. When the application data identification symbol 'F0th' is detected, the mounted tape is decided to be the DRAW type tape. In initialization, the DRAW type tape is confirmed to be the unused tape not subjected to initialization and the initialization of the tape is carried out and the recorded information is not erased. In recording operation, the recording is carried out after confirmation that the groups to be recorded are the groups incremented with the last-group and the magnetic tape is subjected to high-accuracy DRAW recording of the fresh information without the erasure of the already recorded information.

摘要： PROBLEM TO BE SOLVED: To load a tape cassette quickly. SOLUTION: When a tape cassette is loaded to a tape streamer drive, an MIC is checked (S001). If the result is 'OK', i.e., an MIC is equipped and no communication error is present, a system data is read out from the MIC (S002) and a physical tape characteristic ID is detected thus obtaining tape length information, tape thickness information, and the like. If the result of MIC check is 'NG', i.e., an MIC is not equipped or a communication error is detected, a magnetic tape is traveled and a transition is made to a processing for detecting a system area recorded on a magnetic tape (S006). If a system area is detected on the magnetic tape, the physical tape characteristic ID is detected therefrom (S008). If a system area is not detected on the magnetic tape in step S006, the magnetic tape is traveled and the tape length is measured (S009).

摘要： PROBLEM TO BE SOLVED: To improve drive operation characteristics for a tape cassette by reading management information to be stored in the memory of the tape cassette and storing it as backup data and then similarly updating the backup data when the management information needs to be updated. SOLUTION: Data in a Memory In Cassette(MIC) is verified at a specific point, and the data in the MIC is updated by a backup data when the data is not appropriate. As a result, it can be grasped whether the management information data in the MIC is appropriate or not and at the same time by writing backup data that is accurate at that time, the data in the MIC can be recovered to a state where appropriate management information is stored when it is judged that the management information in the MIC is judged to be improper or the like. Therefore, even if a situation where the management information data in the MIC is not appropriate occurs, the situation can be canceled, thus preventing trouble to the succeeding operations.
