ABSTRACT:
A head suspension for a disk drive has support plate means (3, 7) serving as a carriage arm and a load beam (5). The load beam consists of a rigid part (13) and a resilient part (15), to apply load to a slider (43) of a head. The support plate means (3, 7) consists of at least layered two plates (3, 7). At least one (7) of the plates (3, 7) has a thickness (t2) appropriate for forming precision holes therethrough by etching. A pivot hole (31) is formed through the plate (7). A loose hole (9) larger than and substantially concentric with the pivot hole is formed through the plate (3). The plates (3, 7) have improved flatness, and the pivot hole has improved accuracy.
