Description

Method and device for storing / detecting track information on analog tape

The present invention relates to a method and apparatus for storing and detecting information in a track of an analog tape, and more particularly, by storing information about the track in a silent portion of the analog tape through a sound source generating device. The present invention relates to a method and apparatus for storing / detecting track information of an analog tape that enables search of an index.

In general, when the user wants to watch or listen to the video or audio signal repeatedly, the analog tape is pressed by pressing the "REW" button during the "PLAY" operation and "PLAY" again in the desired section.

In the case of language learning video tapes, there are many cases where a user wants to repeatedly listen to audio signals rather than an image. However, conventionally, the " PLAY "-" REW "-" " " PLAY " Therefore, the conventional video tape has a cumbersome problem of replaying the tape a number of times if the tape is to be repeatedly heard.

Recently, however, some song tapes that detect information in an analog manner have an AMPS (Auto Music Program Search: AMPS) function. The AMPS function refers to a function of displaying a unique display of a corresponding song previously stored in a silent part at the time of production, and outputting the corresponding song as many times as the user presses the input key by detecting the microcomputer only when the user presses the AMPS input key. However, the user cannot save the information but can only use it for detection.

1 is a block diagram of a procedure for detecting track information of an analog tape to which a conventional AMPS function is added. First, when an AMPS key signal is input to the input unit 31, the control unit 33 prepares to execute the AMPS function. The information detection unit 32 is supported. The controller 33 outputs the information signal selected by the user to the deck unit 34.

The analog tape with the AMPS function can find the next few songs from the currently playing song by using the AMPS function, but the function of obtaining detailed information of the song itself, such as an optical disc, or a song or painting desired by the user. Since there is no easy function to find sentences by simple operation, it is more cumbersome and inconvenient for the user than the optical disk digital method.

Accordingly, an object of the present invention is to solve the above problems, and to store the information on the track in the silent portion of the analog tape through the sound source generating device, the track and index of the analog tape to enable search A method and apparatus for storing / detecting track information are provided.
