本考案は磁気記録再生装置に係り特に２台の磁気記録再
生装置を用いて再生又は録音する場合の継ぎをスムーズ
に行なう様にした磁気記録再生装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording and reproducing device, and more particularly to a magnetic recording and reproducing device that allows smooth transition between reproduction or recording using two magnetic recording and reproducing devices.
近年ＦＭ放送が盛んになりその品質、ｍｆｆ１（Ｓ／Ｎ
歪率等）も良いものが要求され音響放送等の多くは磁気

は１０インチリール２巻を必要とし、実際の録音又は再
生に於ては２台の磁気記録再生装置を用いて１台の１巻
目のリールの再生終予後に２台目の２巻目のリールを再
生する様にしている。In recent years, FM broadcasting has become popular, and its quality, mff1 (S/N
Because of the demand for good distortion (distortion rate, etc.), most audio broadcasts are broadcast by playing back what has been recorded on magnetic recording and reproducing devices, but the tape speed of these devices is 38C from a performance standpoint.
Wl/sec, even if you use a 10-inch reel that can wrap the maximum number of tapes, you can only record or play for about 30 minutes; for example, when broadcasting a one-hour program, two 10-inch reels are used. In actual recording or playback, two magnetic recording and reproducing devices are used so that when one device finishes playing the first reel, the second device plays the second reel. ing.
この場合特に音楽などの演奏に於て途中で１巻目のリー
ルと２巻目のリール継ぎ部分が来ると、どうしても不自
然な音を発することに成り、音楽をスムーズに演奏し得
ない。In this case, especially when playing music, if the joint between the first reel and the second reel comes in the middle, an unnatural sound will inevitably be produced and the music will not be played smoothly.
従来、この様な場合、番組内容を聞き乍ら２巻目をスム

終り部分にセンシングテープ等を貼付けるかキュー信号
等を記録して、これらエンド信号によって２巻目のリー
ルをスタートさせているので内容がどこかで途切れる様
になりスムーズに再生出来ない欠点を有していた。Conventionally, in cases like this, the program was either forced to start the second reel smoothly while listening to the program content, or pasted a sensing tape or the like at the end of the first reel, or recorded a cue signal, etc. Since the second reel is started by these end signals, the contents tend to be interrupted at some point and cannot be played back smoothly.
本考案は上述の如き欠点を除去した磁気記録再生装置を
提供するもので、１巻目のリールと２巻目のリールの再
生をスムーズに行ない得る様にしたものである。The present invention provides a magnetic recording and reproducing device which eliminates the above-mentioned drawbacks and is capable of smoothly reproducing the first reel and the second reel.
本考案の特徴とするところはプログラム用のトラックと

ードを記録する再生時、その記録されているタイムコー
ドを再生し、１巻目のテープと２巻目のテープのタイム
コードを比較し、同期をとり、同期がとれた時点で再生
出力を切替える様にしたものである。The feature of this invention is that the time code (address code) is recorded separately from the program track, and the time code (address code) is recorded a little before the end of the first reel (during playback, the tape of the first reel and the tape of the second reel are recorded). (Time required to synchronize reel tape)
Put the second tape in recording mode = Intersection - Record the time code During playback, play back the recorded time code and compare the time codes of the first tape and the second tape. Then, synchronization is established, and the playback output is switched when synchronization is achieved.

る。First, when the first magnetic recording/reproducing device 3 is put into a recording state, a signal from the recording input terminal 1 is applied to the first and second tracks 8a and 8b of the magnetic tape 8 shown in FIG. 8C, the output from the time code oscillator 2 is recorded. Such recording continues for 30 minutes, and shortly before the 30 minutes have elapsed, at the time of reproduction, the first magnetic recording/reproducing device 3 and the second magnetic recording/reproducing device 3
When, for example, 29 minutes and 30 seconds have passed after the time required for the second magnetic recording and reproducing device 4 to harmonize, the second magnetic recording and reproducing device 4
Start the recording mode and record for 30 minutes.
この場合第１の磁気記録再生装置３は３０分経過する迄
録音状態を保持する。In this case, the first magnetic recording/reproducing device 3 maintains the recording state until 30 minutes have passed.

成される。The playback time of the first magnetic recording and playback device 3 is, for example, 29 minutes 3
When the time reaches 0 seconds (since the time code is being reproduced, the elapsed time can be easily detected), the second magnetic recording/reproducing device 4 is started by the control circuit 5, and the tape 8 of the first magnetic recording/reproducing device 3 is started. The tape speed of the second magnetic recording and reproducing device 4 is controlled so that the time for outputting the time code recorded on the tape 8' of the second magnetic recording and reproducing device 4 is equal to the time for outputting the time code recorded on the tape 8' of the second magnetic recording and reproducing device 4. When the phase is adjusted and the synchronization is achieved, the switching circuit 13 is operated and the first
The output of the second magnetic recording/reproducing device 3 is switched to the output of the second magnetic recording/reproducing device 4, and a signal is output to the output terminal 14.
