Abstract

　記録ディスクに向き合わせられるヘッドアクチュエータ部材（２１）の先端にロードタブ（２４）は支持される。記録ディスクの外側にはランプ部材（２５）が固定される。ランプ部材（２５）には、所定の曲率で描かれる円弧に沿ってロードタブ（２４）の通路が区画される。通路に沿って磁極が配列される。ロードタブ（２４）がランプ部材（２５）上の通路に沿って移動すると、電磁変換素子はランプ部材（２５）上の磁極を読み出す。磁極の変化に基づきランプ部材（２５）上でロードタブ（２４）の位置は特定される。位置と経過時間とに基づきロードタブ（２４）の移動速度は特定される。特定される移動速度に基づきヘッドアクチュエータ部材（２１）の揺動は制御される。
