Abstract
A magnetic disk apparatus comprises an access section including a read/write head, for applying to a magnetic disk a recording magnetic field in a gap of the read/write head in accordance with input generation control data. A discriminator discriminates a recording density of the magnetic disk and outputs recording density data representing the recording density to a access controller. The access controller generates and outputs to the access section the generation control data in accordance with input write data and the recording density data from the discriminator.
