Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording / reproducing apparatus effective for use in a video tape recorder capable of recording / reproducing video information and audio information.

[0002]

2. Description of the Related Art In recent years, video tape recorders have achieved a high diffusion rate and are used not only in entertainment but also in fields such as education.

A conventional information recording / reproducing device will be described below. FIG. 3 shows the configuration of a conventional information recording / reproducing device. In FIG. 3, reference numeral 51 is a cassette tape, 52 is a magnetic head, 53 is a video / audio processing unit, 54 is a tape drive unit, 55 is a tape position detection unit, 56 is a control unit, 57 is an operation unit, 58 is a display unit, and 59 is It is a memory.

The operation of the information recording / reproducing apparatus configured as described above will be described below.

First, the type of contents recorded on the magnetic tape used will be described. The information contained in the magnetic tape consists of multiple pieces of information, and the information output by searching the beginning of the next information is recorded depending on the user's selection at the end point or the middle of one piece of information. Has been done. Such an information medium can be utilized in fields such as learning software and game software.

First, the user sets the cassette tape 51 in the video tape recorder. When the reproduction operation is performed by the operation unit 57, the control unit 56 starts the reproduction control and operates the tape driving unit 54 to start the tape running. On the other hand, a reproduction mode instruction is output to the video / audio processing unit 53 to set the reproduction mode. The signal obtained from the magnetic head 52 is converted into a video signal and an audio signal in the video / audio processing unit 53 and output. Further, the current state is displayed on the display unit 58.

Information such as a question that becomes a branch point of information is recorded during reproduction, and when a video / audio output of the information is obtained, the control unit 56 controls the video automatically or by an operation from the operation unit 57. Put the tape recorder in a paused state. Then, when a selection is input from the operation unit 57,
Automatically or depending on the selected contents
The control unit 56 searches until the data of the tape position detection unit 55 matches the data of the start point of the selected information until the start point of the next information selected by the operation from.
This operation is performed automatically or is manually operated by the user while watching the tape position displayed on the display unit 58.

When the target position has been searched, the control unit 56 reactivates the video tape recorder automatically or by operating the operation unit 57. By repeating such operations, it is possible to reproduce a plurality of information recorded on a cassette tape having a plurality of branch points.

[0009]

However, in the above construction, since the tape is wound on the hub, it takes a long time to search, so that information cannot be output during the searching period. There was a problem that the continuity was lost. On the other hand, although the IC memory and the optical disk can be searched in a very short time, the amount of information that can be stored is extremely small as compared with the tape.

An object of the present invention is to solve the above conventional problems and to provide an information recording / reproducing apparatus capable of maintaining recording / reproducing for a long time and information continuity.

[0011]

In order to solve the above problems, the information recording / reproducing apparatus of the present invention comprises a recording / reproducing section capable of recording / reproducing a magnetic tape housed in a cassette tape and wound on a hub, and a cassette tape. A recording / reading unit capable of writing or reading information to / from an IC memory arranged outside and a video / audio processing unit for processing video / audio data in data stored in the IC memory are provided and recorded. The configuration is such that the switching unit for switching between the output of the reproducing unit and the output of the video / audio processing unit in the data stored in the IC memory or the synthesizing unit is the same component.

[0012]

According to this structure, the amount of recorded information is extremely large, but a magnetic recording / reproducing apparatus which requires a lot of time for searching, and the search time is short like IC memory, but the storage capacity is smaller than that of a magnetic tape. The characteristics of both sides are mutually complemented, and the information during the time required for magnetic tape retrieval is
Information can be output in the C memory.
