Abstract: PURPOSE:To achieve retrieval by using a display means for visual information by detecting the no-sound part of an audio signal recorded on a main signal track and address information, relating to the audio signal, recorded on a subsignal track. CONSTITUTION:On the 1st main signal track 2a of a magnetic tape 1, plural pieces of music M1-M3 are recorded with no-signal parts P lied between, and on the subsignal track 3, pieces of address information Q relating to those pieces of music are recorded as digital signals. While the contents of desired address information Q are specified, the no-sound part P on the tape 1 in a high-speed running state is detected and the address information Q in a constant-speed running state is also detected, thereby controlling the running of the tape 1 by the detection signals. Further, the contents of specified or retrieved address information Q are displayed by using liquid crystal, etc., to achieve rapid retrieval by using a display means for visual information.

Abstract: PURPOSE:To display visual information by providing a subsignal track in the center of a tape in its running direction, and by recording blocks of each audio signal of a forward run and relative information alternately on the track. CONSTITUTION:A magnetic tape 1 has the 1st and 2nd tracks 2a and 2b corresponding to a forward run and audio signals are recorded there respectively. Further, one subsignal track 3 is formed in the center of the widthwise direction of the tape 1 along the running direction. Then, the 1st block (a) and 2nd block (b) relating audio signals on the tracks 2a and 2b are recorded alternately on the track 3. In this case, the information relating to the audio signal is recorded as blocks in the form of a digital signal by a start signal S, a data signal D, an end signal E, etc. Thus, the information on the track 3 is displayed on liquid crystal, etc., to display visual information.

Abstract: PURPOSE:To display visual information by reproducing digitized information on a subsignal track, relating to the audio signal of a main signal track, by a subordinate reproducing head and displaying it on a display part through a reproducing circuit part. CONSTITUTION:A tape recorder 10 is equipped with heads which perform recording to and reproduction from main signal tracks 2a and 2b of a magnetic tape 1, and a subordinate recording head and a subordinate reproducing head which perform recording to and reproduction from one subsignal track 3 formed in the center of the tape 1 in the running direction. On this track 3, various pieces of information on audio signals of the main signal tracks are digitized and recorded in the form of numbers, alphabets, etc. Those pieces of information on this track 3 are extracted the subordinate reproducing head and a reproducing circuit part that the recorder 10 has, and then displayed on a display part 21 such as a liquid-crystal display device. Thus, while the audio signals are reproduced, various pieces of visual information relating to them are displayed.

Abstract: PURPOSE:To display visual information by recording subsignals relating to audio signals on a magnetic tape in the running-directional center by using a short- width recording head. CONSTITUTION:Subsignals (a) and (b) relating to audio signals recorded on the main signal tracks 2a and 2b of a magnetic tape 1 are recorded on a subsignal track 3 in the center of the tape in running directions A and B through a subordinate head device 60. This device 60 has a subordinate reproducing head 7 on the up side in the running direction A of the tape 1 and a subordinate recording head 6 on the down side. The heads 7 and 6 each have two head core 61 and 62 opposite to each other with gap parts 63 and 64 between; and the head 7 is made wider than the head 6, and the part except them is provided with a magnetic shield member 65. In the running directions A and B of the tape 1, the subsignals (b) and (a) digitized and made into blocks are reproduced by the head 7 respectively and visual information is displayed by using a liquid-crystal display device, etc.

Abstract: PURPOSE:To prevent degradation of signal information, by storing a vibration- voltage converter and an A-D converter in a microphone case and by taking out an digital output as a microphone output. CONSTITUTION:The acoustic wave is converted to an analogue electric signal by vibration-electric converter 2 in microphone case 1 and is amplified by amplifier 3. The amplified analogue electric signgal is converted to a digital signal by A-D converter 4 and is output through cable 6 to external.
