Head slap detecting device, storage device, head slap detecting method, and computer product |
摘要 |
A head-slap detecting device detects a head slap. The head slap causes a storage medium to be slapped by at least one storage-medium driving unit that performs at least one of reproduction and recording of data from and to the storage medium. The head-slap detecting device includes a detecting unit that detects the head slap by determining whether a first variable gain obtained from a variable gain amplifier that amplifies an output of data reproduced by the storage-medium driving unit exceeds a predetermined threshold.
