摘要： According to an aspect of an embodiment, a storage apparatus includes a judgment unit which judges the clearance between a head and a recording medium. A mode switcher switches from a regular write mode in which data is written on the medium to a write verification mode in which error is checked by reading the data immediately after writing on the medium, where the judgment unit detects a clearance change. A heater control value adjustor corrects for errors detected in the write verification mode by changing a prescribed heater control value for the heater by executing write verifications. An access processor controls the clearance between the head and the medium by heating the head according to the adjusted heater control value, to compensate for operational variables such as low atmospheric pressure.
