Abstract

PURPOSE:To optionally divisionally record audio and video signals on a recording medium by storing a regenerated discontinuous signal out of a rewritable recording medium into a memory and reproducing it as a continuous signal. CONSTITUTION:A control circuit 4 acts to control in such a way that a driving motor 3 is driven, and an optical pickup 2 is operated to reproduce in turn an audio or video signal recorded in skipped places on a magneto-optical disk 1. And, an address generator 5 acts to generate a write address for writing a regenerative signal obtained from the pickup 2 into a RAM 6 based on a signal showing a reproducing place of the disk 1 to be received from the circuit 4 and a read address for read-out. The regenerative signal from the pickup 2 is temporarily interrupted at the time of skip to other place, but the signal is recorded in a continuous address of the RAM 6 and read out, so that it is turned into the continuous regenerative signal.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recording and reproducing apparatus for recording and reproducing audio signals or video signals.

2. Description of the Related Art In recent years, video tape recorders for recording and reproducing video signals and audio tape recorders for recording and reproducing audio signals have become popular, especially digital audio recorders (DAT).
There is a growing demand for a digital signal recording and reproducing device that does not cause signal deterioration even after repeated recording and reproducing operations.

Problems to be Solved by the Invention However, in conventional recording and reproducing devices, even if a recorded signal is erased and there is a place on the recording medium where no signal is recorded, only a signal of the same or shorter length is generated. There were three missing pages at that location that could not be recorded. For example, if you record 10 songs on a magneto-optical disk and then erase the third song, only songs less than the length of the third song can be recorded in that location, and as a result, the recording medium cannot be used. The disadvantage was that the number of unrecorded locations increased.

If data is managed and stored in discrete locations, such as on magnetic disks used in computers, the audio and video signals are continuous signals, so the time it takes for the playback means to travel to different locations on the recording medium is limited. There was a drawback that the signal could be interrupted.

In view of the above-mentioned problems, the present invention provides a recording and reproducing apparatus that can continuously reproduce signals recorded intermittently and that can effectively utilize a recording medium.

Means for Solving the Problems In order to solve the above problems, the recording and reproducing apparatus of the present invention has the following features:
A rewritable recording medium, a recording means for recording an audio signal or a video signal at an arbitrary location on the recording medium, and a reproducing means for reproducing the audio signal or video signal recorded on the recording medium from an arbitrary location. and a recording element that stores the signal reproduced from the reproduction means, and a control means that controls writing and reading of the signal to the storage element according to the position of the recording medium being reproduced by the reproduction means. It is something that

Effect of the Invention With the above configuration, the present invention can realize a recording and reproducing apparatus that can reproduce audio or video signals recorded at discrete locations on a recording medium as a continuous signal.

Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a recording/reproducing apparatus according to the present invention. 1 is a magneto-optical disk for recording audio or video signals; 2 is an optical pickup for reproducing the signals recorded on the magneto-optical disk 1; The control circuit 4 drives the drive motor 3 to control the optical pickup 2 to successively reproduce audio or video signals recorded at discrete locations on the optical disc 1. The address generator 5 receives and receives from the control circuit 4 a signal indicating the location of the magneto-optical disk being reproduced from the optical pickup 2, and transfers the reproduced signal obtained from the optical pickup 2 to the RAM.
(Random access memory) Generates a write address to be written to 6 and a read address to be read from RAM. The reproduced signal obtained from the optical pickup 2 is temporarily interrupted when the optical pickup 2 jumps to another location on the magneto-optical disk, but once it is stored at consecutive addresses in the RAM and then read out, it becomes continuous. A reproduced signal is obtained.

Alternatively, the signals may be stored in the RAM at discrete addresses and read out at discrete addresses so that the signals are continuous.

Although the above description has been made regarding the case where one magneto-optical disk is used as a recording medium, a plurality of magneto-optical disks may be used and divided into a plurality of magneto-optical disks to record signals.

As is clear from the above explanation, since the present invention converts a continuous signal that has been reproduced intermittently into a continuous signal using a storage element, the recording medium is not limited to a magneto-optical disk, but can also be used, for example, as a magnetic terrorist disk. ,, -; -B may also be used.

Effects of the Invention As described above, the present invention can convert a reproduced discontinuous signal into a continuous signal using a memory, so that continuous audio signals and video signals can be placed at any position on a recording medium. Can be divided and recorded. Therefore, if you use a large-capacity recording medium, even if you record hundreds of pieces of music in any location and delete them when they are no longer needed, the deleted location will be one of the storage locations for the next song to be recorded. Since it can be used as a tape recorder, the medium can be used effectively, and unlike conventional tape recorders, there is no need to be conscious of where on the tape to record songs.
