Abstract
An improved read/write head carriage assembly for use with a floppy disk recorder including a rigidly mounted head-carrying arm, a pivotally mounted head-carrying arm, a damper assembly for limiting the excursion and damping the motion of the pivotally mounted arm, and a pair of protective sleds, each affixed to an arm.
Claims1
A read/write head carriage assembly for a disk recorder comprising:
- a carriage member;
- an arm pivotally affixed to said carriage member for movement toward and away from a loaded position;
- disk engaging means affixed to said arm;
- means for biasing said arm toward said loaded position at which said disk engaging means is loaded in compliance with a suitably disposed disk;
- and
- damping means coupled between said carriage member and said arm for damping motion of said arm toward said loaded position:
- said damping means including a bifurcated stop member having first and second finger portions disposed in spaced-apart relationship, and a blade which is at least partially disposed between and frictionally engaged with said finger portions so as to spread apart said finger portions, thereby developing an opposing frictional force in response to motion between said stop member and said blade, whereby the motion of said arm toward said loaded position is damped.
