摘要： A recording system that is automatically triggered in response to the detection of a triggering event to record a desired signal. In order to determine whether the triggering event is present in the input signal, the recording system of the present invention detects whether a recognized pattern in the input signal corresponds to a reference pattern maintained in memory. Alternatively, the triggering event may be detected by performing a predetermined logic operation on those recognized patterns that match at least one of the reference patterns. The present invention also employs a buffer for delaying the input signal by a predetermined duration. Once the triggering event is detected, a recording device is activated to record the delayed signal for at least the predetermined duration.

摘要： PURPOSE:To detect positioning well only with rotary heads in a recording and reproducing device of a PCM signal by making the frequency of a positioning pilot signal in a recording position, which should be positioned at a reproducing time, different from that in other parts at a recording time. CONSTITUTION:The device is set to the quick traversing or rewinding reproducing mode simultaneously with turning-on of a positioning switch. At this time, a pilot signal P1 or P2 taken out from a tape is supplied to a low pass filter 41 and is extracted and is supplied to a detecting circuit 42, and the change from the signal P1 to the signal P2 having a frequency f2 is detected. Consequently, a detection signal SD of the signal P2 is obtained from this detecting circuit 42 when the position of the signal P2 recorded between musics at a recording time is detected; and if the signal SD has a prescribed level or higher, a detection output signal is led out to an output terminal 44, and the tape is set to the normal reproducing mode from the quick traversing or rewinding mode in the position to be positioned by the output signal. Thus, positioning is performed only with rotary heads.
摘要翻译：目的：通过将定位导频信号的频率设置在记录位置，通过将位于再现时间的定位导频信号的频率与其他部分的频率不同，才能通过旋转磁头在PCM信号的记录和再现装置中良好地检测定位录音时间。构成：在定位开关打开的同时，将设备设置为快速移动或倒带重放模式。此时，从带取出的导频信号P1或P2被提供给低通滤波器41，并被提取并被提供给检测电路42，并且从信号P1到具有频率f2的信号P2的改变被检测到。因此，当检测到记录在记录时间的音乐之间的信号P2的位置时，从该检测电路42获得信号P2的检测信号SD; 并且如果信号SD具有规定的等级或更高级别，则检测输出信号被引出到输出端子44，并且在快速移动或重绕模式中将带设置为正常再现模式输出信号。因此，仅使用旋转头进行定位。

摘要： PURPOSE:To shorten the lead-in time of a running control servo system for a magnetic tape by detecting which area a tape stop position is in on the basis of the comparison output between two pilot signals and the switching signal of a magnetic head. CONSTITUTION:Two pilot signals in a reproduced signal from a reproducing means are supplied to a signal level detecting circuit 30 to detect the levels of the two pilot signals, separately. A comparator 9 compares the levels of the two input signals with each other, and outputs a high-level or low-level signal according to the comparison result. A detection signal output circuit 40 detects which of areas obtained by dividing one period by track pitch the stop position of the tape is in on the basis of the comparison result between the levels of the two pilot signals and the switching signal of the magnetic head. Consequently, the lead-in time of the servo system is shortened.

摘要： PURPOSE:To detect a tape stop position with high precision by outputting which area the tape stop position is in or how far the stop position is from one terminal of the area by the level comparison output between two pilot signals and the switching signal of a magnetic head.

摘要： PURPOSE:To perform efficient running control when driving state of a magnetic tape are changed, by detecting a stop position of the magnetic tape from comparison outputs obtained by comparing the amplitude of four pilot signals in a reproduced signal. CONSTITUTION:The reproduced signal of a magnetic head is supplied to the input terminal of a balanced modulator 6, and a signal f1 or f2 for generating a beat signal of frequency f1-f2 f3-f4=fa or f1-f4 f2-f3=fb with a pilot sig nal in the reproduced signal is inputted thereto as well in response to the switching controller of a switch circuit 12. The output signal of the modulator 6 is separated into signals fa and fb through BPFs 7a and 7b. The signals fa and fb are supplied to detectors 8a and 8b to generate signals with corresponding amplitudes, whose levels are compared with each other by a comparator 9. An output signal O1 based upon the comparison result appears at an output terminal 14. This signal O1 indicates the stop position of the magnetic tape according to whether the pilot signal inputted to the modulator 6 is f1 or f2.
