no. 1 example

[0042] In the first embodiment, the buckle member 1 is in contact with the buckle stopper member via the contact protrusion member 19 . The volume of the snap member 1 in the vicinity of the contact portion is smaller than that of hitherto known snap members. As a result, the coefficient of restitution between the buckle member 1 and the buckle stopper member is high since the contact protrusion member 19 is twisted in the case of receiving an impact. That is, by adjusting the volume of the contact protrusion member 19, the spring coefficient between the actuator member and the actuator stop member is equal to that between the buckle member 1 and the buckle stop member. In this way, in case the driver receives a rotational shock, the actuator member and the snap member 1 receive the same angular acceleration, and rotate. As a result, the locked member of the actuator member and the locking member 3 of the snap member 1 are locked together, and the rotation of the actuator mem...

Abstract

This recording medium drive has an actuator member which rotationally moves around a first shaft, a latch stop member fixed to the housing, and a latch member which rotationally moves around a second shaft. The actuator member, having a locked member, and the latch member has a locking member which restrains the rotational movement of the actuator member and a coefficient of repulsion between the latch stop member and the latch member is a coefficient of repulsion such that, in the event that the housing receives an impact when the actuator is in a standby state, the locking member of the latch member reaches a lockable rotation angle before the locked member of the actuator member reaches the lockable rotation angle. In the event that various impacts are applied, it is possible to prevent the actuator member from jumping out to the recording medium.

Description

technical field [0001] The present invention relates to recording medium drives such as hard disk drives. More particularly, the present invention relates to a snap member that limits rotation of an actuator member of a recording media drive having a ramp member in response to an impact. Background technique [0002] Currently, for example, in a hard disk drive, a magnetic recording medium is rotated at high speed. Then, air is sucked between the head slider and the magnetic recording medium, and the head slider is floated by the pressure exerted by the air. At this time, the magnetic head located at the front end of the head slider maintains a distance of 20 nm or less from the magnetic recording medium. Then, the magnetic head performs reading and writing of media information. [0003] There is a Contact Start and Stop (CSS) method that brings a head slider into contact with a non-recording area of ​​a magnetic recording medium and keeps it stationary during non-operati...
