    • PURPOSE:To reduce the required time for retrieval operation considerably by comparing and calculating the information from a tape position arithmetic means and a retrieval mode switching position calculation means and switching the retrieval control means from the ultrahigh speed mode into the PNO-ID retrieval mode. CONSTITUTION:A tape position arithmetic means 6 calculates the position of a tape driven at present with a reel pulse during the retrieval operation continuously, and the position of the tape driven at present is compared with a retrieval mode switching position obtained by a retrieval mode switching position calculation means 12 with comparare arithmetic means 13 while being driven. A program number identification signal PNO-ID on the tape up to the retrieval mode switching position is not read while the tape is driven in the ultrahigh speed drive mode 11a. When the tape reaches the retrieval mode switching position, the retrieval control means 11 is switched to the PNO-ID retrieval mode 11b, the drive speed slows down and the tape is driven at a high speed while reading the PNO-ID on the tape, a start part of an object retrieval PNP is retrieved. Thus, the required time for the retrieval is considerably reduced.

    • PURPOSE:To prevent excess action and to obtain contents information rationally and effectively by searching contents information by cue action at beginning edge of a tape or by review action in another case. CONSTITUTION:A head amplifier 22 amplifies a signal from a rotary transformer 4 and a demodulating circuit 23 separates of output of the head amplifier 22 mixing a recording signal, contents information, count value, etc. A microcomputer 24 includes a part of a beginning edge part detecting means 9, a part of contents information reproducing means 10, a part of a count value reproducing means 11 and a control means 13 of a mechanism 7. When the magnetic tape 1 is loaded, it becomes contents information searching action, and searching contents information is done by cue action in case of beginning edge part of the tape and by review action in case of the parts on its way to record. As finding out contents information, a PLAY action is executed and contents information is reproduced to store into a RAM 25 as a contents information memory means 12. When the contents information is not found and prescribed time passes, the selection of heading of the first recording signal is executed.

    • PURPOSE:To perform high-grade consecutive recording and editing which need no mechanical phase-adjusting function by the use of two-head digital audio tape recorders. CONSTITUTION:Two magnetic recording/reproducing devices are connected for recording and reproducing. When a consecutive recording instruction is given to the recording side, the consecutive recording control means 48 instructs the tape travel control means 45 to start the reproduction of the consecutive recording tape a little in advance of the consecutive recording connection point and reads the tape time code. At the same time, it takes out the reproduced output for monitoring from the pre-recorded memory means 42 in advance of the time code of the tape by a specified interval of time required for correcting the delay occurring in the digital signal processing means 41. When the output reproduced from the memory reaches the position corresponding to the consecutive recording connection point, the consecutive recording control means 48 sets the recording mode on the recording side and issues a memory reproduction starting instruction to the reproducing side, which actuates the reproducing function immediately after the connection point and inputs the tape data accumulated in the memory means 42 to the recording side as reproduced output.

    • PURPOSE:To efficiently display many pieces of mode setting information by sharing a display area for both a signal level display and a mode display and properly arranging the area. CONSTITUTION:When a display switching commanding means 13 commands the mode display side, a display device is switched to a mode display state. In such state, a mode information storage means 16 stored with a mode setting state set by a mode setting means 17 takes out mode setting information and a mode display converting means 15 converts the information into data corresponding to a bar graph display state. Since a display switching means 12 is switched to a mode display side with a command from the display switching means 13, a part of bar graph display signal level data of the conversion output is replaced with the mode setting information and the resulting data are outputted to a bar graph display means 11. Consequently, the display device become a mode display state wherein a signal level and the mode setting information are displayed at the same time.

    • PURPOSE:To arrange that musical signals or the like dispersed on a plurality of tapes can be dubbed on one tape simply, freely and automatically by a method wherein different and peculiar machine Nos. are set on a plurality of replay-only machines and a recording-only machine and a control machine issues both machines Nos. and operating instructions. CONSTITUTION:A replay-only machine 1 is constituted of replay operation-mode reply means 1a, a music No. search means 1b, a one-piece replay means 1c and a machine No. judgment means 1d. Replay-only machines 2, 3 are constituted in the same manner. A control machine 5 is constituted of a replay control means 5a, a recording control means 5b, a programming means 5c, an input means 5d and a machine No. instruction means 5e. While a plurality of replay- only machines 1 to 3, a recording-only machine 4 and one control machine 5 are used, different and peculiar machine Nos. are set on the plurality of replay-only machines 1 to 3 and the recording-only machine 4, and the control machine 5 issues both machine Nos. and operating instructions. Thereby, musical signals or the like dispersed on a plurality of tapes can be dubbed on one tape simply, freely and automatically.
