HEAD GIMBAL ASSEMBLY HAVING A RADIAL ROTARY PIEZOELECTRIC MICROACTUATOR BETWEEN A READ HEAD AND A FLEXURE TONGUE |
摘要 |
A novel head gimbal assembly (HGA) includes a piezoelectric microactuator having a first side and an opposing second side. The first side includes a plurality of anchor regions that extend radially from a center point and are bonded to the gimbal tongue. The first side also includes a first plurality of non-bonded regions lying between the anchor regions. The second side includes a plurality of link regions that extend radially from the center point and are bonded to a top surface of the read head. The second side also includes a second plurality of non-bonded regions lying between the link regions. Each of the plurality of link regions is angularly spaced between two of the plurality of anchor regions. |
