Abstract

PURPOSE: To avoid the deterioration in quality of a reproduced image, by warning when the remaining amount of a tape is short and letting a user designate a tape speed. CONSTITUTION: When a cassette is inserted, a microcomputer 3 calculates the remaining amount of a tape, stores the amount and displays via a display circuit 7 to a television screen or a VTR display panel. When a program to be recorded is preselected, the microcomputer 3 detects whether or not the program can be completely recorded to the tape from a programmed time length, the tape speed and the remaining amount of the tape. If the program cannot be perfectly recorded, that is, the tape is short, a buzzer 6 is sounded and the fact is displayed. At this time, the tape speed is designated through a ten key of a remote controller 1. If the tape is still short with this designated speed, the buzzer 6 is sounded in the same manner as above and, the programmed recording is terminated while the display screen is kept to alarm the fact. When the cassette is replaced or the tape is rewound, the above sequence of operations is carried out again from the beginning.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus including magnetism.

[0002]

2. Description of the Related Art Whether to use the automatic tape speed switching function called auto REC or just REC is selected in advance in the function setting mode. ing. In addition, even if you make full use of the same function, it does not warn you that the recording will run out, so it is unkind. Further, when the same function is exercised, the image quality is deteriorated on the playback screen of the tape speed switching portion. Therefore, it is unkind that it is not possible to select the same function.

[0003]

To eliminate the disadvantages of the prior art, that is, to avoid recording loss due to a shortage of tape as much as possible, and to give a warning to that effect. Further, the user is made to select whether the reproduction image quality deterioration of the tape speed switching part due to the execution of the tape speed automatic switching function is selected, or whether the reproduction speed deterioration of the tape speed switching part is avoided by setting the lowest tape speed from the beginning.

[0004]

[Means and Actions for Solving the Problems] When the recording reservation is made, the tape remaining amount data is always referred to, and it is judged whether or not the recording is cut off due to the shortage of the tape to warn the result.
At the same time as displaying, it is calculated whether or not the recording loss occurs at all tape speeds including the auto mode, and the result is displayed.

Based on the result, the user is made to specify the tape speed again.

[0006]

EXAMPLE An example of the present invention is shown in FIGS. Immediately after the cassette is inserted, the microcomputer 3 calculates the remaining tape amount, stores the result in 312 in the memory 31, and displays it on the TV screen display 71 and the VTR front panel display 72 via the display circuit 7 (illustrated). None). The following examples 1 and 2 are selected in the VTR function setting menu.

Example 1 ... When recording is reserved, the microcomputer 3 calculates the presence or absence of recording interruption based on the reservation time length, the reserved tape speed, and the tape remaining amount value, and the buzzer 6 only when the recording interruption occurs.
Sound and the TV screen display 71 of FIG. 3 and V of FIG.
The display as shown in TR front panel display 72 is performed. Next, if the tape speed selected by the user with the 10 key on the remote controller 1 causes the recording to end, the buzzer 6 is sounded and the recording reservation is ended while leaving only the display like 711 and respecting the user's intention. 3 in memory 31
The determined tape speed is stored in 11. If the tape is rewound or the cassette is replaced in the middle, restart from the tape remaining amount calculation.

Example 2: When a recording reservation is made, the microcomputer 3 calculates whether or not the recording is ended based on the reserved time length, the reserved tape speed, and the remaining tape value. In this case, the buzzer 6 is sounded and a message indicating that the automatic recording mode is set is displayed on 71 and 72 (not shown).
“Auto” is stored in 11. In the case of automatic recording, if there is a recording cutout, a message such as "The tape will be insufficient for 30 minutes even with automatic recording" is displayed on 71 and 72 (not shown), the recording reservation is finished, and "311" in the memory 31 is displayed in "Auto." ”
Is stored. If the tape is rewound or the cassette is replaced in the middle, restart from the tape remaining amount calculation.

[0009]

[Effects of the Invention] It is necessary to avoid recording loss due to a shortage of tape as much as possible, and if it cannot be avoided, give a warning to that effect. In addition, let the user select whether to deteriorate the playback image quality of the tape speed switching part due to the execution of the automatic tape speed switching function or to set the lowest tape speed from the beginning to avoid the deterioration of the playback image quality of the tape speed switching part. Can be done.
