Description

Analog tape with track information

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic tape in which information is formatted on tracks of analog tapes. More particularly, the present invention relates to an analog tape having track information in which information about the tracks is recorded on a silent portion of the analog tape to enable search of tracks and indexes. It is about tape.

In general, if an analog tape user wants to watch or listen to a video or audio signal repeatedly, the user presses the "REW" button during the "PLAY" operation to return the tape and "PLAY" it 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 " operation must be repeated as many times as desired, regardless of the video signal and the audio signal. 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.

In addition, a general analog tape is composed of a silent portion 12 between songs added with an AMPS function as shown in FIG. 2, and a track 11 leading to the next song or sentence after the silent portion 12 ends. have.

Fig. 1 is a block diagram showing 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 is ready to execute the AMPS function. Then, with the support of the information detection unit 32 for information detection, the control unit 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 of searching for 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, by recording information about the track in the silent portion of the analog tape, track and index analog tape having track information that allows for quick search and detection To provide.

An analog tape having track information of the present invention for realizing the above object includes a plurality of track portions in which program data for reproduction are recorded, and information in which information about the contents of the program is connected between the tracks and the tracks. It is characterized by consisting of a storage.

Hereinafter, a configuration and an embodiment of the present invention will be described with reference to the accompanying drawings.

3 and 4, an analog tape having track information according to the present invention can be divided into two areas, and a plurality of program data for storing a desired song or a sentence for learning a foreign language are recorded. Tracks 51 and an information storage 52 which connects the tracks with the tracks and records information about the contents of the program. In particular, the information storage 52 has a total of 24 bits. Information about the table of contents of the first information unit 91 of 8 bits, which indicates the total number of tracks, the second information unit 92 of 8 bits, which indicates the current track, and the contents of the second information unit. It consists of an index part 93 of 8 bits to be displayed.

The first information section 91 is composed of a direction detecting bit 82 for indicating the direction in which the tape is played and a total amount bit 83 for indicating the total number of tracks. The information unit 92 is a blank (BLANK) 84 of one-bit silencer to distinguish it from the first information unit 91, and a progress track unit 85 consisting of 7-bits containing information about the track currently in progress. It consists of).

In addition, the index unit 93 composed of the last 8 bits is to be listened to by repeating the blank (BLANK) 84 of the 1-bit silent part and the current track for each part to distinguish it from the second information unit 92. This is for use when the index is set in the front and rear silence of the desired sentence or word, it is composed of a 7-bit progress index 86 required to search the index.

The direction detecting bit 82 is pulses 53 and 54 which are input to the control unit 33 to detect the direction in which information travels, to synchronize the starting point of each track, and to proceed during playback or storage of the tape. There are two lead pulses, a forward pulse 53 with a lead pulse LEAD PULSE for detecting the direction and a reverse pulse 54 indicating the opposite direction.
