Storage apparatus, storage medium, and control method and program of storage apparatus

Abstract

In a storage medium to which information is recorded by using a write head of an inductive type, in addition to a servo section in which servo information is recorded and a data section to which data is to be written, a write training section on which training write of pseudo-data is to be performed is disposed on a recording track. When the temperature is low, a write control unit writes the pseudo-data to the write training area and then writes data to the data area. By writing the pseudo-data to the write training area, a write core is heated and caused to project toward the medium surface side by thermal expansion, and the writing ability is enhanced; then, the data is written to the data section. A write training section is also disposed in front of a data section in a track of a system area of the storage medium, and, when the temperature is low, and when system information is to be written to the data section of the system area, pseudo-data is written to the write training section.
