Abstract

　ラッチレバー（４１）が第１方向（ＤＲ１）に回転すると、ラッチ部材（４３）は第４回転方向（ＤＲ４）に回転する。ラッチ部材（４３）はヘッドアクチュエータ組立体（３２）の移動経路（Ｐ）に進入する。ヘッドアクチュエータ組立体（２１、３２）の回転は規制される。ヘッドアクチュエータ組立体はランプ部材上に保持される。ラッチレバーが第２方向（ＤＲ２）に回転すると、同様に、ラッチ部材は第４回転方向（ＤＲ４）に回転する。ヘッドアクチュエータ組立体の回転は規制される。記録ディスク駆動装置に外部から衝撃が加わっても、ヘッドスライダは確実に記録媒体の外側に保持されることができる。しかも、段差面（５３）上に空間が確保される。この空間内でラッチレバー（４１）は移動することができる。ボイスコイルモーター（２７）の変位は回避される。ボイスコイルモーターの縮小は回避される。ラッチレバーやラッチ部材の設計の自由度は確保される。
