Abstract of the Disclosure A magnetic disk apparatus includes a head disk assembly, a servo control circuit, a head positioning microprocessor, a sector pulse generating circuit, and a main controller. The head selection circuit selects any one of disk media in a data read/write operation. The servo control circuit controls an operation of a head positioning motor. The head positioning microprocessor controls an operation of the servo control circuit based on an external command. The sector pulse generating circuit has a plurality of sector counters for counting a clock signal and generating sector pulses having different periods, selects one of the sector pulses from the sector counters based on an input selection signal, and outputs the selected sector pulse always with a predetermined separation or longer. The main controller controls an information write/read operation through the head selection circuit based on the sector pulse output from the sector pulse generating circuit, and outputs a selection signal to the sector pulse generating circuit, thereby performing switching control of the sector pulse.
