A number of units until the target location is accessed is calculated. It is determined whether there is time for the group of logic to transition from a lower power state to an operational state; the determination is based at least in part on the number of units between a current location of a read head associated with the hard disk system and the target location which is different from the current location of the read head and a warm up time associated with the group of logic. If it is determined there is time, the group of logic is put into the lower power state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"On demand hard disk drive system on a chip power control scheme","description":"An access instruction associated with accessing a target location in a disk is obtained.
