ACTUATOR FOR HARD DISK DRIVE

摘要

PURPOSE: An actuator for hard disk drive is provided to uniformly maintain a deflation phenomenon by installing a plurality of connection body to an inner bobbin located at an inner side around a coil. CONSTITUTION: An arm(102) and a bobbin(120) are oppositely formed around a body (101) in which a pivot bearing (101a) is installed. A suspension(103) has a head(104) and is installed to a side portion of the arm(102). The head(104) installed to a side portion of the suspension(103) is loaded on each disk. The bobbin(120) has an outer bobbin(122) and an inner bobbin(123), and a coil(121) is installed between the outer bobbin(122) and the inner bobbin(123). A rib(123a) is formed to a boundary portion of the inner bobbin(123) and the coil(121). A plurality of connection bodies(125) are formed for connecting a center portion(124) of the inner bobbin(123) to a certain portion of the rib(123a).
