記録媒体に対してデータの書き込み又は読み取りを行うピックアップを移動させるためのスレッド機構を具備したディスクドライブ装置であって、
前記スレッド機構を駆動させるためのスレッドモータを制御するモータ制御手段と、
前記モータ制御手段に供給する駆動電圧を所定の電圧値に切り換えることができる駆動電圧切換手段と、
装置の動作状態に基づいて前記駆動電圧切換手段を制御する駆動電圧制御手段と、
を備えていることを特徴とするディスクドライブ装置。 A disk drive device comprising a sled mechanism for moving a pickup for writing or reading data on a recording medium,
Motor control means for controlling a thread motor for driving the thread mechanism;
Drive voltage switching means capable of switching the drive voltage supplied to the motor control means to a predetermined voltage value;
Drive voltage control means for controlling the drive voltage switching means based on the operating state of the device;
A disk drive device comprising: 前記駆動電圧切換手段は、少なくとも、前記スレッド機構を確実に駆動させるために必要な第１の駆動電圧値と、前記スレッド機構の駆動に最小限度必要な第２の駆動電圧値とを切り換える機能を具備していることを特徴とする請求項１に記載のディスクドライブ装置。   The drive voltage switching means has a function of switching at least a first drive voltage value necessary for surely driving the sled mechanism and a second drive voltage value required to drive the sled mechanism to a minimum. The disk drive apparatus according to claim 1, further comprising: 前記駆動電圧制御手段は、前記スレッド機構の駆動不良を検出すると、該スレッド機構を確実に駆動させるために必要な駆動電圧を供給するように前記駆動電圧切換手段を制御すること
