The present invention provides a disk drive apparatus for recording and/or playing back a signal onto and/or from a disk-shaped recording medium. The disk drive apparatus has a configuration comprising a head arm for supporting a magnetic head. The head arm is provided with an arm base made of a rigid material and a suspension implemented by a plate spring. Since in the configuration of the disk drive apparatus provided by the present invention includes a head arm which is provided with an arm base made of a rigid material and a suspension implemented by a plate spring, the length of the suspension can be shortened and the positional precision of the magnetic head can be assured with a high degree of reliability.
