Abstract

【課題】保持部材、駆動装置、ピックアップ装置、並びにディスク装置において、磁性部材に対するコイルの感度を向上させる。 【解決手段】コイルが装備される保持部材に関する。コイルに対向する磁性部材にコイルを近づけることが可能な近接促進部を備えた保持部材を構成させる。近接促進部は、コイルが備えられる保持部材本体のコイル装着部の基準面部から保持部材本体の外側に向けて隆起された突出部とされることにより、磁性部材に生じる磁場が効率的に利用され、磁性部材に対するコイルの感度が向上する。前記保持部材と、保持部材に装備されるコイルと、コイルに対向する磁性部材とを備えた駆動装置を構成させる。前記保持部材と、保持部材に装備されるレンズと、保持部材に装備されるコイルと、コイルに対向する磁性部材とを備えたピックアップ装置を構成させる。
