Abstract
An apparatus includes a data storage disc having a read/write surface, and an arm extending along an arm axis and having a head end that supports a head that is configured to interact with the read/write surface. The apparatus also includes a rail extending along a rail axis that is normal to the arm axis, and a carriage coupled to the arm and movably coupled to the rail. The apparatus further includes a latch mechanism configured to releasably hold the carriage to the rail at a fixed position.
Claims20
A data storage device comprising:
- a data storage disc having a read/write surface defining an x-y plane;
- a ramp adjacent to an outer diameter of the data storage disc;
- and
- a linear actuator assembly comprising:
- a rail extending along a rail axis and having a first engagement member;
- a carriage movably coupled to the rail and having a second engagement member configured for coupling to the first engagement member;
- an arm coupled to the carriage and extending along an arm axis that is normal to the rail axis, the arm having a head end that is movable relative to the data storage disc by movement of the carriage along the rail in the x-y plane, wherein the arm is coupled to the carriage at an end of the arm that is opposite to the head end of the arm;
- and
- a head supported by the head end of the arm, wherein the head is configured to communicate with the read/write surface when positioned at the data storage disc, and wherein the head end of the arm is configured to be supported by the ramp when retracted away from the data storage disc;
- wherein the first and second engagement members are configured to couple together proximate to the end of the arm that is opposite to the head end of the arm when the head end of the arm is supported by the ramp, thereby latching the carriage to the rail.
