CARRIDGE ASSEMBLY AND STORAGE MEDIUM DRIVING DEVICE

摘要

In a carriage assembly (16), a support arm (32) is extended in parallel to the linear region (33a) of a coil (33). The support arm (32) is extended to the outer region than the outer end in the radial direction of the linear region (33a). Consequently, the rigidity of a coil support comprising the support arm (32) and a frame body (34) is enhanced by the support of the support arm (32). According to the verification by the inventors, the gain of the frequency characteristics of the coil support is remarkably reduced. Moreover, the resonant frequency of the carriage assembly (16) is made higher. The resonance of the carriage assembly (16) can be suppressed.
