Abstract: PURPOSE:To polish accurately a piezoelectric element up to an objective inherent frequency without substantially receiving an effect of high and low levels of a signal, by integrating and discharging a fixed level of voltage in response to the polarity of difference between two filter outputs and detecting the peak of the integration output to stop polishing. CONSTITUTION:A signal containing the inherent frequency component of crystal bar 4 is delivered from an amplifier 10 by polishing. This signal undergoes level control through an AGC circuit 11 and is supplied to a distributor 12 as well as to filters 13 and 14. When the output of a differential amplifier 19 is lower than a level O, an output is generated from a comparator 21. Meanwhile an integration circuit 22 performs charging with a fixed time constant. On the other hand, a comparator 20 produces an output when the output of the amplifier 19 higher than the level O. As a result, the above-mentioned charging output is discharged with a fixed time constant. A stop signal is produced from a control circuit 27 to complete the polishing by the output generated from a comparator 25 at a peak point (f) obtained after the circuit 27 is set.

Title: Positioning method for magnetic head
Inventor: IWAKO AKINOBU
IPC: G11B21/08
Filed: 1990-04-06
Abstract: PURPOSE:To speedily and exactly position a magnetic head to track zero by moving the magnetic head to the track side setting an address for several fixed tracks at a time excepting for a format, and afterwards, positioning the magnetic head to the track zero while checking the track address. CONSTITUTION:The track zero is temporarily positioned according to a track zero sensor and the magnetic head is assumed to be positioned at Z1. Next, ID read is executed and the history of the format is checked. In such a case, since there is no format history, the magnetic head is moved to a track 04 inside for eight tracks and positioned at a place securely formated. At such a position, it is checked whether the track address is 00 or not, and since the address is 04, the magnetic head is positioned to the track 00 while executing precise control by track jump. Thus, even when track density is increased, the magnetic head is speedily and exactly positioned to the track zero by effectively providing the track zero sensor.
