Abstract: PURPOSE:To prevent loss from occurring due to the deviation of angle between information data and a magnetic head by adjusting the azimuth angle of the magnetic head for the recording track of a magnetic recording medium so as to always be set zero. CONSTITUTION:An azimuth angle detecting part(detecting part) 2 detects the azimuth angle of the magnetic head 1 from an output voltage when azimuth angle data 5, 6 are read out with the magnetic head 1. The azimuth angle detected by the detecting part 2 is sent to an azimuth angle correction part(correction part) 3, and quantity of correction to set the azimuth angle of the magnetic head 1 at zero is calculated at the part. Calculated quantity of correction is sent to an azimuth angle adjusting part(angle adjusting part) 4, and the angle adjusting part 4 performs adjustment so as to set the azimuth angle at zero by driving the magentic head 1.

Title: Data transmission method
Inventor: MARUYAMA HISAYUKI
Filed: 1987-09-29
Abstract: PURPOSE:To attain multi-stage relay by receiving a clock signal from an external communication network by plural stations in a loop and allowing each station to send a data demodulated from a reception signal in matching with the clock from an external communication network, thereby suppressing accumulation of jitter. CONSTITUTION:Since the phase of a data demodulated from a reception signal is sent while being corrected in matching with the phase of the supplied clock in a station 54 receiving the clock from an external communication network, the data sent from the station 54 has no jitter. Since the relay jitter sent by using a clock extracted from the reception signal by other stations 51-53, 55, 56 is eliminated by the station 54 receiving the clock from an external communication network, the phase deviation of the clock in any of the stations 51-56 is suppressed to a small value and a malfunction due to the phase deviation is prevented. Thus, the accumulation of jitter is suppressed to attain the relay of multi-stage.
