Dual mode independent suspension read/write head assemblies in a hard disk drive |
摘要 |
A disk drive system (70) and an actuator assembly (50; 150) therein are disclosed. The actuator assembly (50) includes multiple actuator arms (52; 152) that are independently rotatable about a pivot pin (26) by the operation of multiple voice coil motors (55; 155). Separate voice coil motor servo controls (94; 194) are provided to control the voice coil motors (55; 155). Voice coil motors (55; 155) may be dedicated to individual actuator arms (52), or alternatively to multiple actuator arms (152) that are connected together. Separate bearings (54; 154) are provided in the actuator assembly (50; 150). The construction of the actuator assembly (50; 150) permits simultaneous read/write access via multiple data channel control circuits (92) associated with individual read/write heads (14). In addition, positioning of an actuator arm (52; 152) during read/write access through a head (14) associated with a different arm (52; 152) is enabled
