1. An actuator for data storage devices, the actuator comprising:
- an actuator arm having a proximal end and a distal end, the actuator arm being rotatable in a rotational plane for supporting a transducer with respect to a data storage medium; and
a head gimbal assembly connected to the distal end of the actuator arm at an inclined angle with respect to the rotational plane of the actuator arm, wherein the head gimbal assembly comprises;
a load beam having a proximal region, a distal region, and a bendable hinge region between the proximal region and the distal region;
a slider for carrying the transducer, wherein the slider includes an air-bearing surface; and
a gimbal connecting the slider to the distal region of the load beam.

Abstract
An actuator arm of a magnetic disc drive having a mounting surface includes a mounting block having a sloped mounting surface. A base plate of a head gimble assembly is attached to the sloped mounting surface. The head gimbal assembly is unbent in its free state and is bent upon being loaded onto the disc.

10. An actuator for positioning a transducer with respect to a storage medium in a storage device, the actuator comprising:
-
a mounting block with a sloped mounting surface wherein the sloped mounting surface is greater than zero degrees, but less than ninety degrees with respect to a top plane of the mounting block so that the sloped mounting surface creates a downward plane; and a head gimbal assembly attached to the sloped mounting surface of the mounting block, wherein the head gimbal assembly comprises; a load beam having a proximal region, a distal region, and a bendable hinge region between the proximal region and the distal region; a slider for carrying a transducer; and a gimbal connecting the slider to the distal region of the load beam. - View Dependent Claims (11, 12)

13. A method of assembling an actuator, the method comprising:
-
attaching an unbent head gimbal assembly to a mounting block with a sloped surface, the head gimbal assembly having a bendable hinge region; and loading the head gimbal assembly onto a data storage medium to create a bend in the hinge region so that a portion of the head gimbal assembly assumes a oncave shape facing away from the data storage medium.
