Provided is an apparatus, medium, and method controlling a flying height of a magnetic head of a disk drive so that a clearance between a disk and the magnetic head in a data write mode can be similar, e.g., substantially the same, as that of the magnetic head in a data read mode. The apparatus may includes a disk storing information, a magnetic head including a magnetic read element detecting a magnetic field on the disk, a magnetic write element magnetizing a portion of the disk, a structure generating an air bearing between a surface of the disk and the magnetic read element and magnetic write element, and a heater heating the structure that generates the air bearing, and a current supply circuit supplying current to the heater so that a clearance between the disk and the magnetic head in a write mode can be similar, e.g., substantially the same, as that of the magnetic head in a read mode.
