One or more methods and systems are presented for performing gain and
timing acquisition of data read from one or more data sectors of a hard
disk drive. The gain and timing information may be used to synchronize a
read channel receiver of the hard disk drive to the data read from the
data sector(s). In a representative embodiment, the one or more methods
comprises determining one or more frequency and phase offsets using one
or more preambles of one or more data sectors residing in a hard disk
drive. In a representative embodiment, the gain of the one or more
preambles may be determined. In another representative embodiment, the
one or more systems used to determine one or more phase and frequency
offsets, and amplitudes, comprise hardware and/or software capable of
utilizing a sequence of consecutive samples provided by one or more
preambles of one or more data sectors.
