Abstract
A latch for locking a drive arm of a disk drive in a parking position comprising: a latch stop having a baffle moveable between an open position and a closed position; and a piezoelectric motor operable to move the baffle between the open and closed positions. When the drive arm is in the parking position it engages the baffle and is prevented from leaving the parking position when the baffle is in the closed position and is not prevented from leaving the parking position when the baffle is in the open position.
Claims14
A latch for a drive arm of a disk drive, wherein said drive arm has a parking position and an operating position and wherein said latch is operable to lock said drive arm in said parking position the latch comprising:
- a latch stop comprising a baffle moveable between an open position and a closed position;
- and
- a piezoelectric motor operable to move said baffle between said open and closed positions,
- wherein said drive arm, in said parking position, engages said baffle and is prevented from leaving said parking position, when said baffle is in said closed position and is not prevented from leaving said parking position when said baffle is in said open position.
A method of locking a drive arm of a disk drive in a parking position using a baffle having an open and a closed position and moving said baffle between said open and closed positions using a piezoelectric motor, wherein when said drive arm is in said parking position and said baffle is in said closed position said drive arm engages said baffle and said drive arm is locked in said parting position, and when said baffle is in said open position said drive arm is free to leave said parking position.
