Method of detecting imbalanced disk in disk drive apparatus and disk drive apparatus |
摘要 |
<p>A method of detecting an imbalanced disk in a disk drive apparatus (10) detects an imbalanced disk at a relatively reasonable cost with high accuracy. In a disk drive apparatus configured to read a signal recorded in a disk by using an optical pickup (11), the method includes a step of determining whether or not the disk is an imbalanced disk based on a signal component of a tracking error signal, which is detected in accordance with push-pull method, depending on a status of the optical pickup. <IMAGE></p> |
