A set of the normal tape portion and the cleaning tape portion is sequentially and repeatedly provided until the end of 1.

Here, all the normal tape parts 3, 5,
A control signal defined by the tape format corresponding to the cleaning tape 1 is cleaned on the control tracks 13, 14, 15, 16, 17, 18 on one end side in the width direction of 7, 8, 10, 12 by cleaning. It should be recorded in advance when the cassette 1 is manufactured.

Normal tape parts 3, 5, 7, 8, 10, 12
Are control tracks 13, 14, 15, 16, 1
The following two types of data formatted based on the control signals recorded in Nos. 7 and 18 can be recorded. That is, the control data 20 for controlling the cleaning operation and the history data 30 in which cleaning history information is collected can be recorded.

On the other hand, in the control data 20, a cleaning tape identification flag 21 for distinguishing a normal tape from a cleaning tape, a cleaning tape part of the same set as the normal tape part, and a cleaning tape part of a time group are unused or used. A cleaning tape portion used flag 22 for identifying whether the tape has been used and an end flag 23 for indicating the end portion of the cleaning tape are provided.

On the other hand, the history data 30 includes the date and time of cleaning 31, the ID number 32 for identifying the tape recorder using the cleaning tape, the number of times the cleaning tape has been used 33, and the number of times the current tape recorder has been used 3.
4. The user area 35 that can be programmed by the user from the computer side through the interface of the tape recorder, the error rate measurement pattern 36 by which the tape recorder side can evaluate whether the error rate is improved before and after cleaning, A memo random area 37 in which arbitrary items can be recorded is provided. Here, the length of each cleaning tape portion is adjusted so that one cleaning time is about 20 seconds.

Further, as shown in FIG. 2, the tape recorder 40 normally uses the cleaning history data 30 on the tape portion.
Can be recorded and the recorded cleaning history data 30 can be reproduced. A recording / reproducing circuit 41, a normal tape portion data write detection circuit 42 for writing or detecting data in the normal tape portion, and a control signal for controlling the cleaning operation. And a cleaning history data memory 44 for holding the cleaning history data 30.

The cleaning tape 1 and the tape recorder 40 configured as described above operate as follows. As shown in FIGS. 3 to 4, when a cassette tape having the normal tape portion (#N) as the tape position is inserted into the recording / reproducing circuit 41 of the tape recorder 40 in step S1, the normal tape portion (#N) is inserted in step S2. It is determined whether or not the control signal is recorded in N). If the control signal is not recorded, the tape is sent in the rewinding direction in step S3, and the process returns to step S2.

If there is a control signal in step S2, the process proceeds to step S4, in which the normal tape data write detection circuit 42 detects the cleaning tape identification flag 21, and it is determined whether the tape is a normal tape or a cleaning tape. If so, normal operation is performed in step S5, and if it is a cleaning tape, step S6
Then, the normal tape data writing detection circuit 42 detects the cleaning tape portion used flag 22 of the cleaning tape portion (#N) to determine whether it has been used or not.

If it is determined in step S6 that the tape has been used, the tape is fast-forwarded to the next (# N + 1) normal tape portion in step S7, and the process returns to step S6. Step S
If it is determined in step 6 that the tape is unused, the recording / reproducing circuit 41 reproduces the normal tape portion (#N) in step S8, and the normal tape portion data write detection circuit 42 reproduces the last time (#
It is judged whether or not the history information up to (N-1) has been recorded. If not recorded, the previous (# N-1) normal tape portion is rewound in step S9, and the process returns to step S6.

If the history data 30 up to the previous time (# N-1) has been recorded in step S8, the system controller 43 proceeds to step S10 to evaluate the reproduction of the error rate before cleaning based on the error rate measurement pattern 36. Then, the process proceeds to step S11
The cleaning history data 30 up to -1) and the error rate before cleaning are stored in the cleaning history information memory 4
4 and then, in step S12, the normal tape portion data write detection circuit 42 sets the used flag 22 of the cleaning tape portion (#N) and records it in the normal tape portion (#N).

After the process of step S12 is performed, the process proceeds to step S13, where the tape is run in the normal reproducing state, that is, the recording / reproducing circuit 41, and the normal tape portion (#
Head cleaning is performed by advancing the tape from N) to the end of the cleaning tape portion (#N).

In step S14, the recording / reproducing circuit 41 determines whether or not the control signal of the normal tape portion of the next time (# N + 1) is detected, and the next time (# N +
It is determined whether or not the position of the normal tape portion of 1) has reached the position of the head (not shown) of the recording / reproducing circuit 41, and this determination is repeated until the position is reached, and the control signal of the normal tape portion (# N + 1) is detected. By doing so, it is determined that the tape has progressed to the normal tape portion (# N + 1), the progress of the tape is stopped in step S15, and head cleaning is completed.

Next, in step S16, the system controller 43 evaluates and reproduces the error rate based on the error rate measurement pattern 36 after cleaning. In step S17, the previous (#N) stored in the cleaning history data memory 44 is stored. The cleaning history data 30 of this time (#N) is added to the cleaning history data 30 of -1) and recorded on the normal tape portion of the next time (# N + 1).

Then, the process proceeds to step S18,
Next time (# N + 1), the tape is rewound to the position of the beginning of the normal tape portion, the cassette tape is ejected in step S19, and the process ends in step S20.

As described above, if it is determined in step S6 that it has been used, the next (#N
The tape is fast-forwarded to the normal tape portion of (+1) and the process returns to step S6.
By detecting the used flag 22 of the cleaning tape portion (# N + 1) according to 2, it is determined whether it is used or unused. In this way, the tape is sequentially fast-forwarded until an unused cleaning tape portion is detected, and if detected, the judgment and processing are executed according to the sequence of steps S8 to S17.

Since the control signal is recorded on the normal tape portion, the normal tape portion can be detected by detecting the control signal even in the fast-forwarding or rewinding state. Further, the head and the tape are not in sliding contact with each other in the fast-forwarding or rewinding state, and a gap called a so-called air film is generated between them, so that the head is not excessively cleaned by passing through the cleaning tape portion. .

As described above, when the cassette tape having the normal tape portion (#N) as the tape position is inserted into the recording / reproducing circuit 41 of the tape recorder 40 in step S1, the normal tape portion (# It is determined whether or not the control signal is recorded in N). If the tape position at the time of insertion is the cleaning tape portion,
The tape is rewound, and it is determined whether or not the control signal is recorded on the closest normal tape portion (herein referred to as #N), and the determination and processing are performed according to the sequence from step S2.

At this time, when the closest normal tape portion (#N) is judged and processed in accordance with the sequence of steps S2 to S6, when it is judged to be used in step S6, it is fast-forwarded. Judgment and processing are performed from the first detected normal tape portion of the unused portion in accordance with the sequence from step S8 described above.

Here, when the closest normal tape portion (#N) is judged and processed according to the sequence of steps S2 to S6, when it is judged as unused in step S6, it is rewound. Judgment and processing are performed from the first detected normal tape portion of the used portion in accordance with the sequence from step S8 described above.

As described above, the recording / reproducing circuit 41 reproduces the normal tape portion (#N) in step S8, and the normal tape portion data write detection circuit 42 reproduces the history data up to the previous time (# N-1). If it is not recorded, it is determined in step S9 that the last time (#
N-1) Rewind to the normal tape part and perform step S
6, when the cleaning history data 30 is not recorded, it is not at the beginning of the unused cleaning tape portion, the used flag is not set, and the history data 3
Since the normal tape part in which 0 is recorded is the unused head part, the tape is rewound in sequence until the unused normal tape part is detected first, and the beginning of the unused normal tape part is searched.

When up to the M-th group of cleaning tape parts (#M) of the cleaning tape 1 in the above-mentioned sequence is used, the history data 30 of all the cleanings using the tape is the M + 1th group of normal tape parts (# M +).
It is recorded in 1). Therefore, step S
By executing steps 1 to S11, the cleaning history data 30 can be read out and used for maintenance management of the tape recorder.

Here, the maintenance management of the tape recorder is performed, for example, by associating the correspondence between the cleaning tape and the tape recorder to prompt the user with a warning that the cleaning tape will be required after how many hours have been used. Say. These are effective, for example, when a robot performs maintenance management on an unmanned vehicle equipped with a plurality of tape recorders called cart machines.
