Title: Digital servo device
Inventor: OGINO TSUKASA
IPC: G11B7/085
Filed: 1990-02-23
Abstract: PURPOSE:To exactly control a head without being affected by friction and external force by calculating level difference by sampling a servo error signal within a prescribed amplitude level, and calculating the velocity of the head from this calculated value, the time of a sampling interval and a track pitch. CONSTITUTION:A servo error signal tracking error detector 3 samples the servo error signal within the prescribed amplitude, and a DSP (digital signal processor) 8 calculates the level difference. Then, the velocity of a head 2 is calculated from this calculated value, the time of the sampling interval and the track pitch. Therefore, even when the head 2 approaches a target position, the velocity can be exactly detected. Thus, since the velocity of the head 2 is made exact, the seek operation of the head is exactly controlled and because of closed loop control, there is no influence of friction or the external force.

Abstract: PURPOSE: To reduce the number of drive voltage levels to simplify the voltage power source and lower the voltage level of the drive voltage by making equivalent the peak voltage value to be applied to a block electrode and a segment electrode.  
     CONSTITUTION: The electrode of a liquid crystal bar graph display plate 4 is composed of a block electrode 5 and a segment electrode 6 thereby to light only one segment 7. The electrodes 5 and 6 constitute a matrix wiring to connect the terminals B 1  to B 4  and S 1  to S 4  with the drive device 8. Analog switches 9 and 10 are connected with the respective terminals and are controlled by a decoder 13 such that either one of the switches is always turned on. Under the off condition of the block, a voltage of VBB=VO and 2VO is applied whereas a voltage of VBA=3BO and 0 is applied under the active condition. On the other hand, the segment 7 to be lit under the active condition is supplied with the voltage VSB=0 and VO whereas the segment left unlit is supplied with the voltage VSA=2VOand VO. With these drive waveforms, the voltage levels are 3VO, 2VO, VO and 0, and the maximum peak voltage level is 3VO, which is three quarters of the conventional one so that the voltage source can be simplified while reducing the voltage level.
