ABSTRACT:
A task assigning system within a dual actuator disk drive system wherein each task has a cylinder address comprising a plurality of registers, each register having a unique address and a plurality of fields for storing a task including the cylinder address associated with the tasks, a queue comprising a header register, the header register having a plurality of fields, an insertion means for inserting and ordering the registers into the queue when a task is first stored into the register, a first means for assigning tasks stored in the queue to a first actuator of the dual actuators in the sequence of increasing value of the cylinder addresses of tasks stored in the registers in the queue and a second means for assigning tasks stored in the queue to a second actuator of the dual actuators in the sequence of decreasing values of the cylinder addresses of the tasks stored in the registers in the queue.
