摘要: PROBLEM TO BE SOLVED: To reduce labor of a design engineer hard disk device or the like.SOLUTION: A digital control part 100 generates drive voltage command signal DDRV in response to current value (VCMCRNT and detection DIVCM, D/A converter 101 an analog ADRV from DDRV. driver output 102 drives motor VCM resistance Rs ADRV. When VCMCRNT is between positive threshold negative threshold, arithmetic 108 internal VCMFS_i first state "1", controls gain amplifier 103 "H". Otherwise, small second "L".
