摘要： An address translation unit is provided for logical to physical address conversion. In particular, apparatus and method are described for receiving a logical cylinder head sector for a logical block address and converting it into a physical cylinder head sector. If a logical block address is received, it is converted to a physical block address and then the physical block address is converted into a physical cylinder head sector. If a logical cylinder head sector is first received, it is converted into a logical block address, and then the conversion takes place just as it would for an initially received logical block address.
