Abstract

PURPOSE:To reproduce information from the beginning without performing any winding operation of a magnetic tape by loading a cassette half housed in a cassette housing part in turn into a mechanism part and housing the cassette half under a program searched state, which is required if the magnetic tape is not program-searched, into the cassette housing part. CONSTITUTION:When a control part 5 of the magnetic recording and reproducing device is supplied with a program searching signal for program searching on the magnetic tape of a cassette half, the cassette half housed in the cassette housing part are loaded in turn into the mechanism part 6, and whether the magnetic tape is program-searched or not is decided based on a detecting signal to be outputted by a tape sensor 4, and when the magnetic tape is program searched, the mechanism part 6 is controlled in order to house the cassette half into the cassette housing part. However, when the magnetic tape is not program-searched, after the program searching is performed by rewinding the magnetic tape, the mechanism part is controlled in order to house the cassette half into the cassette housing part. By this method, the information can be reproduced from the beginning without performing the rewinding operation of the magnetic tape.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention involves loading a cassette half stored in a cassette storage section into a mechanical section, and transferring information, such as music, to the magnetic tape stored in the cassette half. The present invention relates to a magnetic recording and reproducing device that records and reproduces information recorded on a magnetic tape.

[Conventional technology]

A conventional magnetic recording/reproducing device loads a cassette half stored in a cassette storage unit capable of accommodating multiple cassette halves into a mechanical unit based on the output of an operating unit, and reproduces information recorded on a magnetic tape. In this case, the magnetic tape housed in the cassette half is run in that state to reproduce the information recorded on the magnetic tape.

[Problem to be solved by the invention]

Conventional recording and reproducing devices are configured as described above, so when reproducing information recorded on a magnetic tape with a cassette half loaded in the mechanical part, the magnetic tape is not necessarily located at the beginning, so for example, When a predetermined amount of magnetic tape is wound on a take-up reel, information is reproduced from where it left off previously.

Therefore, when reproducing information recorded on a magnetic tape from the beginning, there is an inconvenience in that it is necessary to operate the rewind key on the operation section to find the beginning of the magnetic tape.

Furthermore, when the magnetic tape of the cassette half is a digital audio tape, there is an inconvenience that the table of contents information recorded at the beginning of the magnetic tape cannot be read.

The present invention has been made to solve the above-mentioned inconveniences, and provides a magnetic recording and reproducing device in which a magnetic tape is stored in a cassette storage section with the beginning of the magnetic tape being located prior to reproducing information recorded on the magnetic tape. It provides:

[Means to solve the problem]

The magnetic recording and reproducing apparatus according to the present invention includes a cassette sensor that detects when a cassette/ent half is loaded into a mechanical section, and a tape sensor that detects the state of a magnetic tape stored in the cassette/ent half that is loaded into the mechanical section. When a cue signal is supplied to cue the magnetic tape of the cassette halves, the cassette halves stored in the cassette/gutter storage section are sequentially loaded into the mechanical section, and the magnetic tape is detected based on the detection signal output by the tape sensor. Determine whether the magnetic tape is at the beginning, and if the magnetic tape is not at the beginning, rewind the magnetic tape, locate the beginning, and then move the mechanical part to store the cassette half in the cassette storage section. It is equipped with a control section for controlling.

[Function] When the control unit of the magnetic recording and reproducing apparatus according to the present invention is supplied with a cue signal for cueing the magnetic tape of the cassette halves, it sequentially loads the cassette halves stored in the cassette storage portion into the mechanical portion. Then, based on the detection signal output by the tape sensor, it is determined whether the recording magnetic tape is located at the beginning, and if the magnetic tape is located at the beginning, the mechanical section is controlled to store the cassette half in the cassette storage section. do.

However, it is determined whether the magnetic tape is cued based on the detection signal output by the tape sensor, and if the 6R tape is not cued, the magnetic tape is rewound and cued, and then the cassette half is inserted. The mechanical section is controlled to store the cassette in the cassette storage section.

Note that whether or not the cassette half is loaded into the mechanical section 6 can be determined based on the loading detection signal of the cassette sensor 3.

When the cassette half is loaded, it is determined whether or not the magnetic tape is located at the beginning based on the detection signal of the tape sensor 4 (step 5T4). If the magnetic tape is not located at the beginning, the mechanical section 6 is activated. Step 5T5) of rewinding the magnetic tape as rewind mode, step ST
