In addition, the modes of the offset tape recorder 1 and the force set tape recorder 2 are detected by the operating state detection circuits 59 and 60, respectively, and are supplied to the video RAM 28 to be displayed on the receiver 3, such as [PLAY]. By displaying the characters "REC", you can easily check the mode of the tape recorder.
Accidents such as erroneously shifting to another mode can be prevented.

Playback of Cassette Tape Next, a case will be described in which the songs copied to the tape of the power set tape recorder 2 are played back in order or played back with the order changed.

When the switch 67 provided on the controller 6 is rotated to the force set monitor mode "3" and the cassette monitor switch 66 is closed, a signal is taken out from the drive circuit 44 and the force set tape recorder 2 enters the playback state. The table is run. As a result, the information signal of the song title recorded as an FM signal at the beginning of the tape is extracted in the order of the songs selected and recorded first, demodulated by the FM demodulation circuit 53, and then sent to the serial/parallel conversion circuit 54. After being converted into a parallel signal, it is supplied to the video RAM 28 via the character generator 42, and the song title is displayed on the receiver 3 again. At this time, since the end signal is recorded on the force set tape at the end of the song title information, this end signal is detected by the end signal detection circuit 62 and becomes a stop signal by the drive circuit 44, thereby causing the force setting to start. The tape recorder 2 temporarily enters stop mode. here,
When the light pen 4 picks up the desired playback songs according to the desired playback order, this signal is sent to the command decoder 3.

This causes the force set tape recorder 2 to go into fast forward or rewind mode.

On the other hand, a song interval detection circuit 56 detects the number of unrecorded portions on the set tape, and a song interval counter 63 counts the number of unrecorded portions. The song interval counter 63 is set to count by 1 when the power set tape recorder 2 plays back the song name and enters the stop mode, and a signal corresponding to the number of unrecorded portions is supplied to the comparison circuit 57.
The determination (comparison) circuit 57 compares this signal with a predetermined signal corresponding to the song number stored in the force set reproduction order storage section 55, and it is determined that the signal from the storage section 55 and the signal from the counter 63 match. A detection signal is taken out, and this signal is supplied to the drive circuit 44, whereby the power set tape recorder 2 is put into the play state from the fast forward or rewind mode, and the desired song is reproduced. When a desired song is picked up with the light pen 4, a message such as "N2, N5" is displayed on line 4 on the screen of the receiver 3, as shown in FIG.
, N, . . . ” is displayed, so that it is possible to determine which song is to be played. When the playback of the song is finished, a detection signal obtained by counting the number of continuous unrecorded portions is supplied to the judgment (comparison) circuit 57, where it is compared with the signal from the recording section 55 and the tape is moved to a predetermined position. Then, in the same way as in the above case, a search operation for a song stored in the force set playback order storage section 55 is entered, and the desired song is played back.

At this time, the inter-song counter 63 also operates during fast forwarding or rewinding, but the force set playback order storage section 55 receives a signal instructing the reading of the next track number only when an inter-song interval is detected during play. It is configured to emit. This is done by configuring the time constant in the inter-track detection circuit 56 to be different for fast-forwarding or rewinding and for breaking, so that only the detection output obtained during play is supplied to the cassette playback order storage section 55. Just configure it. In this way, by picking up the songs displayed on the receiver 3 with the light pen 4, desired songs can be reproduced from the dubbing tape in a desired order. During this playback operation, the signal of the track number being played is taken out from the power set playback order storage section 55 and supplied to the color synthesis circuit (or blinking circuit) 58 to obtain a predetermined signal. The number of the song being played, the name of the song, and the required playing time are displayed on the screen, and the line is displayed in a predetermined color, or the text is displayed in color, or the text is made to blink. You can easily confirm which one it is.

As described above, the information block title reproduction and display device according to the present invention reproduces a recording medium in which the title of each information block is recorded at a predetermined position on the recording medium, displays the title signal on a cathode ray tube, and displays the title signal on a cathode ray tube while the recording medium is being reproduced.
