  • Magnetic disk apparatus
    Patent number: 6927947
    Abstract: 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.
