Abstract

PURPOSE:To make a reservation for a weekly program without reserving it each time by recording a program data required for reserving the video recording of the program to a control track of a magnetic tape in relation to a control signal of the device at the time of starting the first time broadcasting and at the time of ending the program. CONSTITUTION:With regard to such a broadcasting program to be reserved repeatedly every week by timer for video recording, when this is broadcast for the first time, a switch 13 provided to a matrix circuit 12 that is connected to a timer CPU 11 is operated at the time of starting the program to store the starting time of the program in a RAM of the timer CPU 11. Then, at the time of ending the program, other program data required for timer video recording is stored in the RAM of the timer CPU 11. Subsequently, the program data stored in the timer CPU 11 is transferred to a system control CPU 14, and a servo circuit 15 is instructed to record it in a specified place of a CTL track provided in a lower row in a magnetic tape loaded in the VTR. By this method, the troublesome reservations of the program data to be repeated every week are dissolved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a magnetic recording/playback device in which program data necessary for recording reservation is recorded on a control track of a magnetic tape used in the device, and the recorded data is The present invention relates to a magnetic recording/playback device that can be used as program data for timer recording.

[Prior Art] In a conventional magnetic recording and reproducing device (hereinafter abbreviated as VTR), for example, if you want to reserve a TV broadcast program for timer recording, you operate the timer recording mechanism provided on the VTR body. There has been a method of reserving a broadcast program using a remote control installed in the VTR body.

In the above reservation method, when making a timer recording reservation for the same program that is broadcast every week, each time you enter data such as the start time (day of the week or date and time), end time, channel number, and tape speed using the numeric keypad or the Up/Down button.
It was set using the Down SW or jog shuttle.

In addition, while setting each of the data several times, there were many cases where the channel number was incorrect.

[Problem to be solved by the invention]

Conventionally, in the timer recording reservation of a VTR, the method of reserving a weekly program using the main body of the VTR or the remote control attached to the main body of the VTR is to set the start time (day of the week or date and time), end time, There was a problem in that each data such as channel number and tape speed had to be set and reserved in the main unit and remote control each time.

Additionally, there is a problem in that the program data may be entered incorrectly while reserving the program several times.

Due to the above-mentioned problems, it has been a challenge to find a method that eliminates the need to reserve program data each time a program is reserved every week.

SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic recording and reproducing apparatus that uses a commonly used magnetic tape for VTRs and eliminates the drawbacks of the conventional apparatus.

[Means to solve the problem]

In the magnetic recording/playback device according to the present invention, when a magnetic tape is used as a recording medium of the device and a repeat timer recording reservation is made every week, the programs necessary for the recording reservation are the day of the week, start time, end time, channel, etc. Among the number and tape speed data, the start time at the start of the first broadcast, the end time at the end of the same broadcast program, the day of the week,
The channel number and tape speed data are each controlled by the controls (
(hereinafter abbreviated as CTL) track, and furthermore, the CTL of the magnetic tape is recorded many times by combining the program data.
The feature is that by recording the program data on a track, the program data can be read out and scheduled for timer recording of the program every week.

[Effect]

The magnetic recording/reproducing apparatus of the present invention is characterized by the recording/reproducing apparatus and the magnetic tape recording method used in the apparatus.

-G, when scheduling a weekly program for timer recording, there are many methods (used) of setting the program's recording mode to 3x mode and recording many times on wooden magnetic tape.

In this case, in the present invention, when there is a broadcast program that you want to record every week, when recording the same broadcast program for the first time, the start time is set at the start of the magnetic tape attached to the VTR, and the end time is set at the end of recording. The program data is recorded on the CTL track of the magnetic tape using the CTL signal generated by the timer recording circuit section of the VTR shown in FIG. By recording the same program data for several weeks, there is no need to set a timer recording program each time after the second time, and the program data is stored in the VTR body or remote control every week. It becomes possible to eliminate complexity.

Timer recording circuit section 1 provided in the VTR shown in FIG.
0, when a broadcast program for which timer recording is scheduled repeatedly every week is broadcast for the first time, the matrix circuit 1 connected to the timer CPU II at the start of the program.
2 is operated to store the start time of the program in the RAM (random access memory is abbreviated) of the timer CPU II. Next, at the time when the program ends, other program data necessary for timer recording, ie, day of the week, end time, tape speed, and channel (hereinafter abbreviated as CH) number, are input by operating the switch 13 of the matrix circuit 12. ,
The timer is stored in the RAM (random access memory is abbreviated) of the CPU II.

Subsequently, the program data stored in the timer CPU 11 is transferred to the system controller CPU 14, and the system controller CPU 14 transfers the program data to the location specified by the CTL track provided at the bottom of the magnetic tape loaded in the VTR. The servo circuit 15 is instructed to record.

The servo circuit 15 turns on and off a servo motor (not shown) in response to commands from the timer CPU II and the system controller CPU 14, controls the speed of the motor, and uses the CTL head 16 to control the magnetic tape. The program data is recorded on the CTL rack provided in the CTL.

Note that when timer recording is performed using the recording reservation data, the system controller CP reads the data recorded on the CTLI-rack using the CTL head 16 and starts recording according to the program data reserved in advance.
U14 has a function of instructing the timer CPU 11 and the servo circuit 15.
