流体力学を応用した光ヘッドーディスク間隔の安定狭細化

抄録

The transverse deflection measurement between a head and a disk varying a lensless head height against Bernoulli base plate under various measurement conditions of dynamic characteristics for the floppy disk are performed. In this experment in order to find a suitable value for both the disk rotation speed and the head hight. both optica method and capacitive method were applied to measure the gap.
