摘要:
A method for driving first and second voice coil motors (VCMs) by generating a first coil current through the first VCM and routing a portion (not all) of the first coil current through the second VCM when a first VCM movement command is commanding greater movement than a second VCM movement command. A second coil current is generated through the second VCM and a portion (not all) of the second coil current is routed through the first VCM, when the first VCM movement command is commanding smaller movement than the second VCM movement command. This may reduce power consumption. Other embodiments are also described and claimed.
