Abstract
The present invention relates to a method of enhancing a preamplifier read recovery in a hard disk drive system and comprises the steps of determining whether the hard disk drive system is transitioning from a non-read state to a read state and initiating a non-read state to a read state transition sequence when a transition from the non-read state to the read state is determined. The transition sequence is independent of a type of non-read state prior to the transitioning. After the non-read state to read state transition sequence is complete the read mode is initiated. In addition, the invention comprises a system for controlling a transition from a non-read state to a read state associated with a preamplifier in a hard disk drive system. The system comprises a detection circuit operable to detect a completion of the non-read state and a non-read state to read state circuit operable to execute a series of events to transition from the non-read state to the read state, wherein the series of events is the same regardless of a type of non-read state. Further, the system comprises a read state initiation circuit operable to initiate the read state after the execution of the series of…
