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.
