Claim:
An actuator adapted to move pivotally to position a head over a rotating recording disk in a disk drive, comprising: a suspension section having a front end portion to which the head is fixed; an arm section connected to said suspension section on a side opposite to the front end portion of the suspension section; a bearing section connected to said arm section on a side opposite to said suspension section and having an aperture adapted to fit a pivot shaft therein; and a coil support section connected to said bearing section on a side opposite to said arm section, said coil support section holding a coil on an inner periphery side thereof, a thickness of the inner periphery adapted to hold the coil being smaller than a thickness of the coil, wherein a first and a second slit are formed in a portion of said bearing section, on the side of said coil support section so as to extend substantially perpendicularly to and toward said pivot shaft, wherein the first slit is formed in a plane parallel to the top surface of the coil support section, and the second slit is formed in a plane parallel to the bottom surface of the coil support section.
