Abstract
A rotary type actuator for a magnetic disk device includes a magnetic head that traverses tracks of the magnetic disk as the actuator rotates about a rotary shaft. The rotary type actuator has at least one arm for the magnetic head at its front end. A first flat cable has one end connected to the rotary type actuator, for making an electrical connection to the electronics in the disk device. A second flat cable is provided on the side surface of the arm, for electrically connecting the magnetic head to the first flat cable. The first flat cable includes a plurality of lands arranged along an extended direction of the arm. The second flat cable includes a first land group provided at one end of the second flat cable for electrically connecting to the magnetic head. The first land group has a plurality of lands arranged along an extended direction of the arm. A second land group is provided at the other end of the second flat cable for electrically connecting to the first flat cable. The second land group has a plurality of lands arranged along the extended direction of the arm, disposed in face-to-face relationship with the lands of the first flat cable, and a lead pattern is provided for electrically connecting the first land group and the second land group. In this manner, the second flat cable overlaps with the first flat cable at the other end.
