Abstract

　アクチュエータの先端部に設けられたヘッドをディスクの外周部近傍に設けられたランプ機構に退避させると共に、アクチュエータのコイル側に設けた強磁性体をラッチマグネットによってラッチするディスク装置において、ラッチ機構の外側のディスク装置の筐体上にシャフトを突設し、このシャフトに風受けアームと補助アームとを備える回動レバーを取り付ける。風受けアームはディスク上に延長し、補助アームの先端部には強磁性板を取り付けておく。ディスクの非回転時には強磁性板はラッチマグネットから離れており、ディスクが回転すると、その風圧が風受けアームを押し、回動レバーを回転させて強磁性板をラッチマグネットに近接させる。この結果、ラッチマグネットと強磁性体との磁性結合が弱まり、ヘッドアクチュエータをラッチマグネットの保持から切り離し易くなる。
