In the case of a tape, the corresponding operation history data is called from the memory 7 and supplied to the tape management information creating circuit 8, and in the case of a cassette tape in which no operation history data is stored, new operation history data is created.

The tape management information creating circuit 8 creates tape management information, that is, reproduced area information and reproduction date and time information from the operation history data supplied from the memory 7.

The method for creating the tape management information will be described below with reference to FIG. FIG. 6 is a matrix diagram showing the operation of the magnetic tape corresponding to each operation content based on the operation data and the tape position data shown in FIG. 5, with the tape position in the horizontal direction and the operation order in the vertical direction. It is a thing. In FIG. 6, the shaded area represents the portion on the magnetic tape that has been reproduced, and the reproduced area information on the magnetic tape can be created by integrating these areas. Furthermore, in this reproduced area information,
By associating the operation date / time data and the operation time data in FIG. 5, the tape management information can be created.

The tape management information thus created is supplied to the display circuit 2 and the reproduction control circuit 9, and the display circuit 2 displays a TV screen as shown in FIG. As a result, the user can easily confirm the past reproduction status of the magnetic tape loaded in the magnetic tape reproducing device 1.

Further, the reproduction control circuit 9 includes the operation switch 3
When the cue signal of the unreproduced area is supplied from the device, the head position data of the unreproduced area on the magnetic tape detected from the tape management information and the position data obtained by the position information output circuit 6 match. The operation of the magnetic tape reproducing apparatus 1 is controlled, and when the data match, the reproduction is automatically performed. As a result, it is possible to perform the cueing reproduction of the unreproduced area of the magnetic tape loaded in the magnetic tape reproducing apparatus 1.

As described above, according to the fourth embodiment, the reproducing means (magnetic tape reproducing apparatus 1) for reproducing the information signal recorded on the magnetic tape, and the operating means (operation switch) for operating the reproducing means. 3), operation data output means (operation information output circuit 4) for outputting the operation content of the operation means as operation data, and time data output means (time information output circuit 5) for outputting date and time as time data. ,
Position data output means (position information output circuit 6) for outputting the absolute position of the magnetic tape as position data, identification means (cassette identification circuit 10) for identifying the magnetic tape and outputting identification data, and the operation means Storage means (memory 7) that creates and stores operation history data from the operation data, the time data, the position data, and the identification data each time an operation is performed, and the operation history stored in the storage means. An information creating means (tape management information creating circuit 8) for creating tape management information from data, a display means (display circuit 2) for displaying the tape management information, and the aforesaid based on the tape management information and the position data. By providing a control means (reproduction control circuit 9) for controlling the reproduction means, the reproduction status according to the cassette tape loaded with a simple structure can be confirmed. Or, it is possible to perform the automatic playback of unplayed area.

Further, the present invention is based on the storage means for creating and storing operation history data, the information creating means for creating tape management information from the operation history data stored in the storage means, and the tape management information based on the tape management information. By providing a control means for controlling the reproduction of the VTR with a simple structure, the operation information (operation time, operation content, tape position at the time of operation) from when the cassette tape is inserted into the VTR to when it is ejected with a simple structure You can create and display cassette management information (playback area information, playback date, tape usage status, etc.) from these operation information and display the unplayed area on the magnetic tape automatically. , Its practical effect is extremely large.

Further, according to the present invention, storage means for creating and storing operation history data, information creating means for creating tape management information from operation history data stored in the storage means, and identification for identifying a magnetic tape. By providing the means, the cassette tape operation information (operation time, operation content, tape position at the time of operation) can be stored with a simple configuration, and cassette management information (reproduced area information, reproduction date / time, etc.) You can create and display the tape usage status, etc., and its practical effect is extremely large.

Further, according to the present invention, storage means for creating and storing operation history data, information creating means for creating tape management information from operation history data stored in the storage means, and identification for identifying a magnetic tape. By providing means and control means for controlling the reproduction of the VTR based on the tape management information, the operation information (operation time / operation content / tape position at the time of operation) of the cassette tape is stored with a simple structure, It is possible to create and display cassette management information (played area information, playback date, tape usage status, etc.) from these operation information, and to automatically play the unplayed area on the magnetic tape. Is extremely large.
