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.
