Magnetic disk apparatus
A technique to be applied to improve the reliability of a magnetic disk apparatus is disclosed. In detail, a magnetic disk apparatus comprises a disk-shaped magnetic recording medium that rotates in operation, a magnetic head for writing the data in the magnetic recording medium and for reading out the data written in the magnetic recording medium, a carriage mechanism having an arm on which the magnetic head is located and moving the magnetic head to an arbitrary position on the magnetic recording medium, a wiring member having wiring, a semiconductor chip having a first main surface and a second main surface that are opposed to each other and electrodes formed on the first main surface, the semiconductor chip being fixed to the wiring member in the state that the electrodes are facing to the wiring of the wiring member, and a housing that contains the magnetic recording medium, the magnetic head, the carriage mechanism, the wiring member, and the semiconductor chip, wherein the edge of the first main surface side of the semiconductor chip and the edge of the second main surface side are covered with insulative resin.
