Accordingly, in the case of a steady running speed of a disk 4, the positive pressure generation surface 3 floats up by a high floating amount, therefore, it comes not to come into contact with the disk by a disturbance caused by distortion of the disk surface, and a projection on the surface. Also, since the head part 1 is deformed by negative pressure, the floating amount of the head part is determined by a balance of positive pressure generated in the head part 1 and negative pressure generated on the negative pressure generation surface 2, and in the head part 1, the floating amount becomes lower than the positive pressure generation surface. In such a way, by a low floating amount, the follow-up property is improved, and wear of the disk can be decreased.

Title: Television radio frequency input circuit
Inventor: YOHANESU HENDORIKUSU HENDORIKU
IPC: H03J5/24
Filed: 1988-07-13
Abstract: PURPOSE: To match the impedance of the input circuit within a reception frequency range by making a 1st series inductor at least an integral multiple larger than other two series inductors. CONSTITUTION: A transforming coil L1 properly reduces the impedance variation of a resonance circuit 11 in a television frequency band at the output ends of 7π type parts C, and L2 and L3 to make it possible to obtain an allowable low-loss impedance match. Therefore, a signal in a 1st television frequency band is supplied to a 1st high-frequency resonance circuit 11 without being accompanied by reflection or the loss of energy by resonance circuits 21 and 31. For a signal of 3rd television frequency, a capacitor C is nearly short- circuited and the value of the transforming coil L1 is set to an integral multiple of the values of the transforming coils L2 and L3, so the transforming coil L1 stops the signal from being supplied to the 1st high-frequency resonance circuit 11.  Consequently, the standing wave ratio at an antenna input terminal can be held within permissible limits in a simple style.
