Disk drive including a delay circuit to provide a delayed reset signal
Abstract:
A disk drive including a delay circuit to provide a delayed reset signal is disclosed. The disk drive includes a head to perform write and read operations to and from a disk and a disk controller that is coupled to the head to control the write and read operations performed by the head. The disk drive further includes: a power loss detection circuit to detect a power loss and to generate a reset signal in response to the power loss; a reset power line coupled to the disk controller and the power loss detection circuit to provide a non-delayed reset signal to the disk controller; and a delay circuit coupled to the reset power line wherein the delay circuit delays the reset signal to provide a delayed reset signal.
