A head support mechanism includes a slider equipped with a magnetic head to read/write
information from/to a magnetic disk, a load beam to provide the slider with an
appropriate load, the load beam being flexible in a direction substantially perpendicular
to the disk, and a microactuator mounting portion equipped with a microactuator.
A first actuator fixing portion, which connects the microactuator mounting portion
to a carriage, and a second actuator fixing portion on the magnetic head side of
the microactuator mounting portion, which connects the microactuator mounting portion
to the load beam, are coupled by two arm portions of the microactuator mounting
portion. The microactuator is mounted on the microactuator mounting portion so
that the microactuator does not come into contact with the microactuator mounting
portion between the first actuator fixing portion and the second actuator fixing portion.
