摘要： PURPOSE:To make the device capable of high positioning accuracy and high positioning speed and to cope with a magnetic disk driving device of a small size capable of high speed access. CONSTITUTION:A magnetic head 20 is driven by a laminated piezoelectric actuator 70 laminated with plural piezoelectric substances for generating distortion. A magnification mechanism for magnifying largely the distortion generated by the laminated piezoelectric actuator 70 and converting the distortion into a deflection angle; possesses two leaf springs 51 and 52, and the magnetic head 20 is fixed to the tips of these leaf springs 51 and 52. Consequently, when a voltage is impressed upon both sides of each piezoelectric substance, distortion proportionate to electric field intensity is generated on each piezoelectric substance to oscillate the tips of the leaf springs 51 and 52. Then, the device is provided with a means for reading out servo information written previously on a magnetic disk 10 and a means for positioning the above magnetic head 20 into a target track based on the said servo information. Consequently, the magnetic disk 10 is controlled based on the servo information, and is sought, and even there is hysteresis on the piezoelectric substance, the magnetic head 20 can accurately be positioned without receiving the above effect.

摘要： PURPOSE:To reduce the power consumption of a stepping motor driver, by changing current, conducted through the coil of a stator, in accordance with the accelerating, decelerating and stopping conditions of the motor. CONSTITUTION:A muCPU 40 sends out a phase direction switching signal PHA to an A phase current control unit 20a and sends out another phase direction switching signal PHB to a B phase current control unit 20b. The muCPU 40 operates the approximate acceleration of a rotor from a switching time, when these phase direction switching signals PHA, PHB are outputted and the step angle of the rotor and inputs the current value of a stator coil into the current control units 20a, 20b through a register 21 and a D/A converter 22 in accordance with the magnitude of the operated acceleration.

摘要： PURPOSE:To position a head with high accuracy by detecting the relative slippage amt. of a spindle index signal and servo pattern and that of the period of the spindle index signal and varying the period of a timer forming a servo synchronizing signal. CONSTITUTION:When a servo reading waveform B is inputted into a comparator 163, its output waveform becomes F and when it is inputted into a comparator 164 it is compared with a reference voltage V2, becoming in a rectangular wave signal D. With this rectangular wave signal D the timer sample signal E of a leading differential waveform is obtd. by an invert circuit 157, flip-flop 158 and AND circuit 159, and inputted to a register 162 to deliver a timer value to muCPU. The muCPU calculates the variation part in the servo pattern and spindle index signal IDX from the value of a read timer 154 and changes the data stored in registers 160 and 161 to bring the sample signal to the center of the servo pattern.

摘要： PURPOSE:To approximately unify a recording density over all tracks by delaying the signal speed of serial data as a track number is large in which the serial data are recorded. CONSTITUTION:The radius RN of a track, in which the value of a track number TR is N, is determined based on the outer diameter, etc., of a recording medium 9 while p-qN, p, q are constant. On the other hand, since the recording medium is rotated at prescribed speed and the recording density of the inner-most side track is constant, when the bit interval of the inner-most side track is TS, a constant K goes to TS/RN. When the period of a clock signal CK is tc, the output data of a ROM 1 corresponding to the track number N is DN and the maximum value of CT 4 is N, TS=(N-DN)/tc is obtained. Since the DN goes to N-(p-qN)K/tc, the output data D of the ROM 1 are selected based on this, and then, the recording density of all tracks can be the same as the recording density of the inner-most side track.
