Abstract
According to one embodiment, a storage device includes a target track write module and a test pattern read module. The target track write module performs a write operation on a target track, which is a predetermined track intersecting a test pattern, on a storage medium to which the test pattern is written. The test pattern intersects a plurality of tracks arranged at regular intervals and is continuously arranged over the tracks. The test pattern read module reads the test pattern overwritten by the target track write module.
