摘要： PURPOSE:To control correctly tracking of a rotary head without being influenced by the mechanical secular change of a device, the temperature change or jittering at the time of double speed reproduction by forming a sampling pulse on the basis of the reproduced output of a pilot signal recorded in the center part of a track every scanning period of each head. CONSTITUTION:A signal taken out from a tape by the rotary heads 1A, 1B is alternately switched by a switching circuit 19 every half rotational period, only a pilot signal is extracted by a band pass filter 20 and its detected output is supplied to sample holding circuits 22, 23. The edge of each pilot signal located on the initial position is detected and a signal S7 is generated. An AND circuit 27 passes only the signal S7 inputted during the period of a window signal S8 and a sampling pulse generating circuit 29 supplies a pair of sampling pulses SP1, SP2 having a phase difference each other to the sample holding circuits 22, 23. An output difference between the sample holding circuits 22 and 23 is taken out from an output terminal 25 as a tracking control signal.

摘要： PURPOSE:To facilitate easy tracking control of a rotary head without using any exclusive fixed head by recording a pilot signal as well as an information signal nearly at the center part in the scanning direction of an oblique track and using the pilot signal in a reproducing mode. CONSTITUTION:Rotary heads 1A and 1B have different azimuth angles, and tracks 4A and 4B of these heads are recorded in a double write mode. The gap width between heads 1A and 1B is larger than the track pitch, and therefore the heads 1A and 1B perform scan over the adjacent tracks. The crosstalk effect of the adjacent tracks can be substantially neglected for the information signal having a high record bit rate owing to the azimuth loss since the adjacent tracks have different azimuth angles. While pilot signals P1-P4 are not attenuated so much by the azimuth loss since the frequencies f1-f4 of those pilot signals are set at a low level respectively and can be reproduced even through the adjacent tracks. Then the traverse speed of a tape 2 is varied in accordance with the difference of outputs of both tracks. Thus the control is possible for tracks.

SOLUTION: In the method and apparatus for detecting reference positions of the annular image taken by the omnidirectional imaging, the radius of a circular pattern is changed while the center is moved in a prescribed region at the center of the annular image taken by an omnidirectional imaging apparatus. Then, the center of a circle most suitable for the inner circle of the annular image is made to be the center coordinate position of the annular image, and the radius of the circle is the radius of the inner circle of the annular image. Further, the radius of the circular pattern is changed on the outside of the inner circle with the center coordinate position as the center of movement, and the radius of a circle most suitable for the outer circle is made to be the radius of the outer circle. In this way, the coordinate position, and positions of the inner circle and outer circle indicating the development region of the annular image taken by the omnidirectional imaging apparatus into the panoramically developed image are found.

Then, coils for signal transmissions 30 are provided on a fixed part 29a so as to orthogonally cross with the coil for power transmission 31. Consequently, leakages of magnetic fluxes to adjacent systems cancel each other and crosstalk among channels can be reduced. Thus, this device enables it to constitute signal systems and a power system in the same coupling rotary transformer without a problem. Consequently, the applying of the device to an equipment handling high frequency signals in a small-sized drum is also made possible.
