Abstract

PURPOSE:To obtain a cassette tape to which video recording index information is added by appending a thermosensitive recording sheet to one part of the housing of the cassette tape and recording the video recording index information on the sheet. CONSTITUTION:The cassette tape 2 is inserted in a magnetic recording and reproducing device 1 from a cassette tape insertion window 13 and fitted at a recording and reproducing position. Meanwhile, a thermal head 14 is retreated to such a position in a path for inserting and fitting the tape that it does not hinder the cassette tape 2 while performing the action of the loading/unloading, the video recording or the reproducing of the cassette tape 2, and it is controlled to move and contact with the thermosensitive recording sheet 15 at the time of finishing the video recording. In such a state, the information such as a video recording start time, a video recording time, a channel, a video recording mode, a sound mode, and a tape counted value, etc., corresponding to a program to be recorded is visually recorded on the thermosensitive sheet 15. Thus, the video recording is finished and the index information corresponding to the video recording is recorded on one part of the housing of the cassette tape.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video recording index recording method that automatically and visually displays index information corresponding to a recorded video signal on a part of the casing of a cassette tape.

[Conventional technology]

When video signals such as TV broadcast programs are recorded using a recording device such as a magnetic recording/reproducing device (VTR), the recording index such as the recording time, recording time, broadcast channel, recording mode, audio mode, tape counter value, etc. cannot be changed by operation. A person writes on the label attached to the cassette tape using a pen or similar method.

Furthermore, instead of writing on the label as described above, it is conceivable to store the recording index in the memory on the recording device side.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, writing the recording index on the label by hand is extremely complicated, and there is a risk that the information may be erroneously transcribed.

On the other hand, the method of storing the recording index information in the memory of the recording device has the problem that it becomes meaningless once the cassette tape is replaced, and it causes confusion to the user.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art described above and to provide a recording index recording method that automatically and visually records a recording index on a part of a cassette tape casing.

[Means to solve the problem]

The above object is achieved by attaching a heat-sensitive recording sheet to a part of the cassette tape and automatically recording recording index information on the heat-sensitive recording sheet using a thermal head provided in a recording device.

[Effect]

Upon completion of recording, index information corresponding to the recording is automatically recorded on a part of the cassette tape housing.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the main parts of a magnetic recording and reproducing apparatus to which the recording index recording method according to the present invention is applied, in which 1 is a magnetic recording and reproducing apparatus, 2 is a cassette tape, 11 is a rotary head cylinder, 12 is a magnetic tape, 13 is a cassette tape insertion window, 14 is a thermal head, and 21 is a cassette tape 2.
The tape protects the lid.

FIG. 2 is a top view of the cassette tape, where 15 is a thermosensitive recording sheet, and the same reference numerals as in FIG. 1 correspond to the same parts.

1 and 2, a cassette tape 2 is inserted into the magnetic recording/reproducing apparatus 1 through the cassette tape insertion window 13 as shown by arrow A in FIG. 1, and is mounted at the recording/reproducing position. The protective lid 21 is opened and the magnetic tape 12 wound inside is wound around the rotary head cylinder 11 by a tape loading mechanism (not shown).

The thermal head 14 is retracted to a position where it does not interfere with the tape insertion and loading path during loading/unloading, recording, and playback operations of the cassette tape, and when recording is finished, it moves to the position shown in the figure, and the thermal head 14 is moved to the position shown in Fig. 2. It is controlled so that it is in contact with the recording sheet 15.

In this state, information such as the recording start time, recording time, channel, recording mode, audio mode, tape counter value, etc. corresponding to the recorded program is visually recorded on the thermosensitive recording sheet 15.

The heat-sensitive recording sheet 15 is a film-like sheet made of a low-molecular organic substance, a resin, and a binder, and visualizes characters and symbol patterns produced by a thermal head. This thermosensitive recording sheet 15 has thermoreversibility in terms of transmittance, and can be recorded at a certain temperature (approximately 67 to 70° C.), and the recording state is maintained even when the temperature is returned to room temperature. Then, when the temperature above the temperature required for recording (approximately 70 to 75 degrees Celsius or above) is applied and the temperature is returned to room temperature, it returns to its original invisible state (opaque).By applying heat to the entire heat-sensitive recording sheet with a thermal head, , can be rewritten any number of times.

Note that the present invention is not limited to the above-mentioned materials, and it goes without saying that a non-rewritable heat-sensitive recording sheet may also be used.

In this way, only a heat-sensitive recording sheet is attached to the cassette tape, and no power source or the like is required for retaining information, making it extremely easy to handle and inexpensive.

〔Effect of the invention〕

As explained above, according to the present invention, since the recording index information can be automatically recorded on the recorded cassette tape, the cassette tape with recording index information added thereto is free from the problems of the prior art and is easy to use. can be obtained.
