Wave torque retract of disk drive actuator |
摘要 |
A disk drive actuator circuit adapted to retract a head assembly when a capacitor discharges energy to the voice coil. This voltage may be modulated to deliver peak torque to get the actuator over a ramp, yet also deliver a lower torque to suppress the initial head velocity when the actuator is over the disk.
