摘要: A data reproducing apparatus for use in a hard disk drive (HDD) reproduces user and servo recorded on disk. The comprises an A/D converter, read PLL circuit, circuit. converter converts signals by head from the disk, to data, both being digital data. circuit generates sampling pulses, which are supplied D/A reproduce In areas provided is recorded, together with preamble patterns uses perform phase acquisition.
