JPS6331083A - Erroneous erasion preventing system - Google Patents

Abstract

PURPOSE:To execute the prevention of an erroneous erasion in an optional position, such as from what part of a tape to what part of the tape it is executed, and to enable the partial prevention of the erroneous erasion and an efficient utilization of the tape by providing a record information file medium on a cassette half. CONSTITUTION:The cassette half 2 has a magnetic tape 1 in it and the record information file medium 3 on the position of a label instead of the label. When a cassette tape is set in a deck to record sound or record picture, at first the deck is made to store the information recorded in a record information file and sound recording or picture recording is made to start and the information is recorded in the record information file medium 3 at the time of finishing recording. If the former deck is used in rerecording picture, rerecording sound or picture can't be executed because of perforations. The deck reads the contents of the recording information file medium 3 and decides whether it can be erased or not and if it can't be erased rerecording sound or picture can't be executed. If it can be erased rerecording sound or picture is executed and at the same time the record information file 3 is updated to new record information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for preventing accidental erasure of audio and video cassette tapes.

[Conventional technology]

Conventionally, this type of accidental erasure prevention method has been used to prevent cassette tapes from being erased.
! By breaking the nail in the hole on the side, you can make 70 skeins.
I made sure that the entire tape was not erased by mistake.

Also, if you want to record again, you have to close the hole (this made it more possible).

[Problem that the invention seeks to solve]

The above-mentioned conventional erasure prevention method judges whether recording is possible on the cassette tape based on whether the hole on the cassette tape is actually open or open, so it is only necessary in some parts. Even if it does exist, it has the disadvantage that it affects the whole body.

[Means for solving problems]

The accidental erasure prevention method of the present invention is based on Taniso's audio.

In a video cassette tape, a recording information file medium is provided on the cassette half in which information such as a name, recording date, and erasable/non-erasable information is stored. Refer to and explain.

FIG. 1 and FIG. 2 are diagrams of one embodiment of the present invention.
2 is a magnetic tape, 2 is a cassette half, 3 is a recording information file medium, and 4 is an example of a recording FRT information file format. An example of the external appearance of a cassette tape is shown below.
-72 contains magnetic tape 1, and there is a label at position 3. Here, the recording information file medium 3 is placed in front of the label at the position of the label. When the cassette tape is set in a device in which the present invention can be carried out and recording is performed, the recorded information is first recorded. Information to be recorded in a file is stored in a deck, audio recording is started, and when it is finished, it is recorded in a recording information file medium 3. Next, break off the hole in the cassette tape's traditional erase prevention hole. When trying to re-record or re-record on this tape, if you try to do so with a conventional deck, it will not be possible to re-record or re-record because of the holes. A deck capable of implementing the present invention reads the contents of the recorded information file medium 3 and determines whether erasing is possible or not. If not, re-recording or re-recording is not possible, and if it is possible, re-recording or re-recording is not possible. At the same time, the recorded information file 3 is updated with new recorded information.

〔Effect of the invention〕

As explained above, the present invention can prevent accidental erasure from anywhere on the tape by attaching a recording information file medium to the cassette half, and can prevent partial erasure from occurring. By reading out the recording information file, you can see at a glance what has been recorded, from where to where.

[Brief explanation of the drawing]

Figures 1 and 2 are diagrams of one embodiment of the present invention.

Claims (1)
