Disk drive suspension in which a pivot center of a slider can be matched with a position of a supporting protrusion when a microactuator element is driven

A disk drive suspension which comprises a load beam and a flexure comprising a stationary part secured to the load beam and a gimbal portion on which a slider is mounted, the disk drive suspension further comprising:

• a pair of microactuator elements disposed on either side of the slider and each comprising a first end portion and a second end portion;
• a pair of first supporting portions of the gimbal portion to which the pair of first end portions are individually secured and supported by the stationary part;
• a pair of second supporting portions of the gimbal portion to which the pair of second end portions are individually secured;
• a first tongue portion which is formed between the pair of first supporting portions and on which a leading-side portion of the slider is disposed for movement;
• a second tongue portion which is formed between the pair of second supporting portions and to which a trailing-side portion of the slider is secured;
• a hinge portion which is formed between the first and second tongue portions, is narrower than the tongue portions, and pivotably connects the tongue portions;
• and
• a supporting protrusion swingably supporting the hinge portion relative to the load beam.
