Description

Magnetic Disc Internal VRC

The present invention relates to a video cassette recorder (hereinafter abbreviated as VSD), and more particularly, to an apparatus that enables to selectively record and play video and audio signals of VSI on a magnetic disk.

In general, a VRC is a device for recording or reproducing a video signal from an external source onto a tape through a rotating head. That is, when the head emitting the magnetic signal and the tape come into contact with each other, the video signal is recorded or reproduced by magnetizing the tape according to the change in the magnetic force of the head.

In addition, the VRC includes a scheduled recording function that enables the user to automatically record a desired broadcast program at a predetermined time, as well as simply play and record functions, based on electronic control according to the recent rapid development of electronic technology. It is also a trend that is widely spread to the public.

The scheduled recording function automatically records a broadcast program even when the user is absent according to the user's reservation information (for example, date, start time, end time, and channel) setting, so that the user can play and watch it next time. It is a beneficial function.

In this case, it is well known that the video cassette must be inserted into the V-Cal at the time of setting the scheduled recording for the reservation of the V-Cal.

However, in the conventional VRC, if the reservation recording was set without inserting the video cassette by a user's mistake, the video cassette had to be inserted in time.

In addition, since only one video tape can be loaded in the conventional VRC, it is impossible to record a desired content from another video tape, and the recording time is also limited due to the limited size of the video tape.

Accordingly, the present invention has been made to solve the above-described problems, and its object is to provide a VRC capable of selectively recording and reproducing an input video / audio signal by embedding a magnetic disk in the deck of the VCD. .

In order to achieve the above object, the present invention provides a recording processing system for recording and outputting a tuner, a TV signal applied from the tuner, and recording a TV signal of the recording processing system on a magnetic tape in accordance with the first recording signal. A magnetic tape deck that reads and outputs a signal recorded on the magnetic tape according to the first read signal, and writes a TV signal of the recording processing system to a predetermined magnetic disk according to the second recording signal, A magnetic disk deck that reads and outputs a signal recorded on the magnetic disk, a reproduction processing system that reproduces and outputs signals output from the magnetic tape deck and the magnetic disk deck, and first and second recording signals according to a user's selection. And a microcomputer for outputting first and second read signals.

In the figure, the key input unit 10 includes a mode selection key for controlling various operations (playing, recording, still, etc.) of V-Cal, a channel up / down key for switching broadcast signals, and the like. A selection key for driving the magnetic disk deck 50 or the magnetic tape deck 40 according to the present embodiment is provided to output a key signal corresponding to the user's key operation.

The tuner 20 outputs a broadcast signal received by tuning to a broadcast channel corresponding to the tuning signal L1 from the microcomputer 80.

In response to the control signal L2 of the microcomputer 80, the recording processing system 30 separates noise and color signals from the broadcast signal input from the tuner 20 into luminance and color signals to record the video signal on a video tape. And amplify the signal, and combine the luminance and color signals into the magnetic tape deck 40 and the magnetic disk deck 50, respectively. The recording processing system 30 also performs signal conversion and amplification for recording audio signals, respectively.

The magnetic tape deck 40 is controlled by the microcomputer 80 for various operations of V-Cal. That is, the T-signal provided from the recording processing system 30 is recorded on the magnetic tape using the rotating head, and the signal recorded on the magnetic tape is read and reproduced in accordance with the control signal L3 of the microcomputer 80. Output to the processing system 60.

On the other hand, the magnetic disk deck 50 according to the present embodiment records the signal applied from the recording processing system 30 on the rotating magnetic disk under the control L4 of the microcomputer 80, or on the magnetic disk. The recorded video and audio signals are read out and output to the reproduction processing system 60.

The reproduction processing system 60 processes the video signal read out from the magnetic tape deck 40 and the magnetic disk deck 50 into a displayable signal according to the control signal L5 of the microcomputer 80. It applies to OSD (On Screen Display) 70. In addition, the reproduction processing system 60 processes the audio signal read out from the magnetic tape deck 40 and the magnetic disk deck 50 into a signal that can be output, and applies it to a speaker to adjust the timing of the audio signal and the video signal.
