摘要： PROBLEM TO BE SOLVED: To provide a device for magnetic recording/reproducing, capable of separating reproducing signals from a plurality of recording tracks obtained by a reproducing head into signals for respective recording tracks.
SOLUTION: During recording, to supply the position information of a reproducing head with respect to a recording track at the time of reproduction, an identification signal having a recording wavelength equal to or more than a minimum recording wavelength and having no interferences between recording tracks is added to a plurality of recording signals to be recorded in a magnetic recording medium. During reproduction, even if signals are reproduced over the plurality of recording tracks of the magnetic recording medium by a reproducing head not corresponding to a recording track width, the position information of the reproducing head is obtained from the identification signal of the plurality of recording tracks, and a reproducing signal is generated for each recording track based on this position information.

摘要： PROBLEM TO BE SOLVED: To obtain an adjusting method by which self-formation of narrow and uniform tracks can be performed by n pieces of rotational recording heads of a magnetic recording and reproducing apparatus. SOLUTION: Treatment for recording a measuring signal and an erasure signal to adjacent tracks in a recordable tape 10 by one recording head HWi of n pieces (i=1 to n) is performed about n pieces of recording heads and the measuring signals are nearly simultaneously recorded on n pieces of tracks by the n pieces of recording heads HW1 to HWn in a normal operation state. Reproducing heads are displaced in a track width direction for the obtained two kinds of tracks and a characteristic curve of a reproduction signal waveform amplitude of the measuring signals to a shift (off-track) amount of the tracks is obtained, a half value width of the characteristic curve is adopted as the track width for convenience' sake and a variable Rioptimum and a variable Rinow corresponding to the width are obtained from respective two kinds of tracks. The position of the recording head HWi is adjusted by an actuator so that the variation of the variable Rinow to the variable Rioptimum is lower than a desirable value. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PURPOSE:To attain stable recording and reproduction by recording a specific tracking reference signal corresponding to an identification signal read at recording mode to make the reference signal equal to the original tracking reference signal.

摘要： PURPOSE:To raise a high speed property and exactitude with regard to a desired track selecting function in a process of a picture access, at the time of video reproducing which corresponds to a special effect containing a still frame reproducing. CONSTITUTION:At the time of still frame reproducing, a movable head 1 is controlled by a track follow-up servo-circuit 9, and picks up and outputs a video signal corresponding to a still frame through a prescribed periodical scanning along a track which becomes an object to be reproduced. A movable head position detecting circuit 2 detects a moving position following the periodical scanning of the movable head 1, generates a signal and outputs it to a sample holding circuit 3. In accordance with the periodical scanning of the movable head 1, a position detecting signal generated in the movable head position detecting circuit 2 and sent to the sample holding circuit 3 forms a saw tooth wave signal corresponding to the periodical scanning of the movable head 1.

摘要： PURPOSE:To put a reproduction head on a normal track in a short time by using an arithmetic circuit which records circularly four types of pilot signals together with the information signal and multiplies the pilot signals themselves in a reproduction mode. CONSTITUTION:The output of an arithmetic circuit 26 is divided into two parts with a proper ratio of amplitude by a dividing circuit 27, and two types of difference frequency signals are separated and extracted through BPFs 28 and 29 tuning with frequencies M and 3M. These difference frequency signals are applied to both input terminals of a differential amplifier 32 via wave detecting circuits 30 and 31 for detection of the difference of both levels. This detection signal is supplied to a polarity switching circuit 33 to receive the inversion of polarity by a track switching signal 14' and every track. Thus it is possible to obtain a tracking control signal 34 having the polarity corresponding to the tracking shift direction and a level corresponding to the degree of the tracking shift. The signal 34 is used to control a capstan motor or to control a rotary head toward the track width direction or the azimuth direction. Thus it is possible to make a head follow a track.
摘要翻译：目的：通过使用将循环四种导频信号与信息信号一起记录的算术电路在短时间内将再现头放在正常轨道上，并将再生模式中的导频信号本身相乘。构成：算术电路26的输出通过分频电路27被分成具有合适的幅度比的两部分，并且通过用频率M和3M调谐的BPF 28和29分离和提取两种类型的差频信号。这些差频信号通过波检测电路30和31施加到差分放大器32的两个输入端，以检测两个电平的差。该检测信号被提供给极性切换电路33，以通过轨道切换信号14'和每个轨道接收极性的反转。因此，可以获得具有对应于跟踪偏移方向的极性的跟踪控制信号34和与跟踪偏移的程度相对应的电平。信号34用于控制主导轴马达或者控制旋转头朝向轨道宽度方向或方位角方向。因此，可以让头跟随轨道。
