Abstract
The present invention is directed to the high speed detection of flaws in a disk drive. In one embodiment, a preamplifier simultaneously receives and processes read signals provided by multiple heads reading a test pattern from multiple disk surfaces to detect flaws in the multiple disk surfaces. In another embodiment, a preamplifier simultaneously provides a write signal to multiple heads that simultaneously write a test pattern to multiple disk surfaces. A further embodiment reduces the time needed to detect flaws by writing a test pattern during servo track writing.
