Abstract

PURPOSE:To attain a simple reproducing operation and to obtain a simple magnetic recorder by providing the 1st magnetic recording medium which records the soft programs on a single or plural tracks of a magnetic recording medium and the 2nd magnetic recording medium which records the video signals on other tracks of the recording medium. CONSTITUTION:A disk 2 contains 50 concentric tracks, for example, and selects one of these tracks for soft programs. While a single picture is recorded on each of other 49 tracks. For instance, a soft program is recorded on the most inner track by a magnetic head 11 and this program gives the video projecting order, time, etc., to a modulator 10 as the digital signals through an input terminal 9. The video signals are obtained by giving the FM modulation to the analog quantity and supplied through an input terminal 4. Then these video signals are recorded on a single track paper screen. A magnetic head 6 moves along the disk 2 by a track motor 8 and selects a track for recording.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording device that records images using a disk-shaped magnetic recording medium on which a plurality of tracks are set.

2. Description of the Related Art As this type of video magnetic recording device, a VTR (video tape recorder), a laser disk device, an electronic still camera, etc. are known. All of these record only images or only images and audio, and the software programs that run the computer are recorded on separate recording media.

Problems to be Solved by the Invention The software program for setting the order and time of displaying images is separate from the recording medium on which the images are recorded, and it is necessary to provide a set position for the software program in the device or This must be stored in the device in advance.

Means for Solving the Problems: A first magnetic recording means for recording a software program on one or more tracks of a magnetic recording medium, and a second magnetic recording means for recording a video signal on other tracks of the magnetic recording medium. A recording means shall be provided.

Function: Since the software program and the video signal are recorded on the same track of the magnetic recording medium, the operation for projecting the video is extremely simple, and the device can also be configured easily.

Example An embodiment of the present invention will be described based on the drawings.

First, a disk 2, which is a disk-shaped magnetic recording medium, is rotatably driven by a motor 1, and a controller 3 is connected to the motor 1. A modulator 5 having an input terminal 4 into which a video signal converted into an electric signal is input is connected to the controller 3, and a magnetic head 6 as a second magnetic recording means is connected to the modulator 5. ing. The magnetic head 6 is held on a horizontal support shaft 7 and is moved by a track motor 8 in a direction perpendicular to the concentric tracks of the disk 2. This track motor 8 is also connected to the controller 3. Further, a modulator 1o having an input terminal 9 for digital signals is provided, and this modulator 10 is connected to the controller 3.
A magnetic helad 11 as a first magnetic recording means fixedly provided to the disk 2 is also connected to the modulator 1o.

In such a configuration, concentric tracks are formed on the disk 2, and there are, for example, 50 tracks, one of which is used for the software I program, and the other For 49 videos, video is recorded at a rate of one image per video.

Therefore, a soft program is recorded on the innermost track by the magnetic head 11. This software program includes the order of images to be displayed, their times, etc., and the signals are applied to the modulator 10 as digital signals from the input terminal 9.

Next, the video signal is an analog signal subjected to FM modulation, and is inputted from the input terminal 4. This video signal is recorded on one track for one screen, and the magnetic head 6
is moved along the disk 2 by a track motor 8,
A track is selected and recorded.

In practice, the magnetic head 11 may be formed to be movable by one track, and the same software program may be recorded on two tracks. As a result, even if there is a dropout in one track, no problem occurs.

Further, it is also possible to provide a larger number of tracks for software programs, and to digitize audio and music and record them on the tracks for the software programs.

This allows you to listen to audio and music when playing still images.

Furthermore, the video signal may also be recorded as a digital signal as the recording signal on the disc 2.

Alternatively, a small computer may be connected to the input terminal 11, and a software program may be created and input using this computer.

Furthermore, it is also possible to apply it to magneto-optical recording means that utilizes laser beams.

Effects of the Invention As described above, the present invention provides a first magnetic recording means for recording a software program on one or more tracks of a magnetic recording medium, and a first magnetic recording means for recording a video signal on other tracks of the magnetic recording medium. Since two magnetic recording means are provided, the video signal and the software program can be recorded on the same recording medium, and the reproduction operation and apparatus can be extremely simplified.
