Title: Magnetic disk pressing mechanism for magnetic recording and reproducing device
Inventor: MORISAWA TAHEI
IPC: G11B17/34
Filed: 1985-12-20
Abstract: PURPOSE:To prevent the inner peripheral part of a magnetic disk from the generation of a flaw due to a stabilizing plate by sticking a soft material which does not hurt the magnetic disk in spite of slidable contact with the magnetic disk to the most inside part of the stable plate in the radius direction of the magnetic disk. CONSTITUTION:When the magnetic disk 11 is supported by a center hub 13 and rotated by a spindle motor 12, the largest floating height h0 is obtained on the center part in the radius direction by an air flow due to the rotation of the magnetic disk 11, but the most outside part and most inside part of the stabilizing plate 15 are floated only by a slight height because of the horizontal leakage of the air flow or the magnetic disk 11 is contacted with the plate 15. Since the most inside part of the plate 15 especially presses the magnetic disk 11 downward, the bending rigidity and floating force are offset each other and the plate 15 may be often contacted with the magnetic disk 11. However, the soft materials 20 are stuck to the most inside and outside parts of the plate 15 and the magnetic disk 11 is slidably contacted with only the soft materials 20, so that the magnetic disk 11 is not damaged.

Abstract: PURPOSE:To make an ultrasonic motor produce no operating sounds when the motor stops. CONSTITUTION:A drive instructing circuit 51 outputs an start signal S1 or stop signal S2 in accordance with an ultrasonic motor turn-on or turn-off instruction inputted against an ultrasonic motor M. When the start signal S1 is outputted, an oscillation circuit 47 starts oscillation and outputs an oscillation signal CL and, when the stop signal S2 is outputted, stops oscillation after outputting the signal CL by 200msec by raising the frequency of the signal. A phase inverting circuit 49 forms a first and second drive signals S4 which are shifted in phase from each other from the signal CL and outputs the signals S4 to a drive circuit 53. The circuit 53 drives the motor M by using the drive signals. At the time of stopping the drive of the motor M, the motor M is driven with a drive signal having a high frequency so as to suppress the generation of progressive oscillatory waves and the motor M slowly stops.
