Abstract
An HDC asserts the read gate of an RDC when a read head is positioned in a sector located before a sector that a hot system instructs to read data when seen from the rotation direction of a storage medium. The data that the read head has read from the sector is used to adapt a circuit that constitutes the RDC. However, the data is not transferred to the host system. Such a process is repeated until the read head reaches a position where data stored in a sector whose data has been instructed to read can be read. In this way, time needed to adapt a circuit that constitutes a read channel can be shortened.
