Abstract

The inability of the lens of an optical disc recorder to focus rapidly may be the salient factor limiting the data transducing rate. In order to provide smooth motion of the focus head and to maximize its speed, a focus lens assembly for an optical disc recorder is resiliently supported by one or more diaphragm springs, and is driven by a magnetic-coil arrangement to focus light onto the optical disc. Each diaphragm spring includes inner and outer support regions connected by a plurality of resilient support arms. Each support arm has straight, parallel sides and extends nonradially.
