Abstract
An alignment testing device comprising a magnetic media with data tracks in nonstandard locations with bidirectionally progressive degrees of misalignment for testing the alignment of the transducer head in a magnetic storage device such as a floppy disk drive. The alignment testing device allows the user to determine the boundaries of track alignments that the transducer head can read, and thereby determine any discrepancy between the heads actual alignment and correct alignment.
