Abstract
According to one embodiment, a magnetic disk device comprises an actuator configured to drive a head stack assembly including a plurality of magnetic heads, a preamplifier connected to each of the magnetic heads with a plurality of traces, and a control section configured to control read/write of the plurality of magnetic heads from/to the magnetic disk through the preamplifier. While a first magnetic head among the plurality of magnetic heads executes a write operation, the control section interrupts access of a second magnetic head in proximity to the first magnetic head to the magnetic disk.

A magnetic disk device comprising:
- an actuator configured to drive a head stack assembly including a plurality of magnetic heads;
- a preamplifier connected to each of the magnetic heads with a plurality of traces;
- and
- a control section configured to control read/write of the plurality of magnetic heads from/to a magnetic disk through the preamplifiers, wherein
- while a first magnetic head among the plurality of magnetic heads executes a write operation, the control section reduces an operating voltage of a second magnetic head positioned in proximity to the first magnetic head, the operating voltage being relative to the magnetic disk.
