A byte wide flaw scan interface is used to identify an characterize flaws in a disk medium. In one embodiment, the associated disk drive ( ) includes head electronics ( ) associated with a disk drive controller ( ) via an NRZ interface ( ). The NRZ interface ( ) is operative for transmitting flaw information for a particular disk address via 8 predefined bit lines. The bit lines have separate definitions for user data sector addresses and servo wedge addresses. By using this byte wide interface, media flaws of various types can be identified and characterized based on a single pass of the transducer head over the disk surface thereby shortening testing times.
