| Zusammenfassung: | The direction in which an information disk apparatus (for example, a DVD-ROM player) is installed is judged without employing a sensor. A controller measures a number of track crossings when a reading unit is moved by a driving unit in a direction corresponding to the radius of an optical disk for a predetermined period of time, and judges a direction in which the DVD-ROM player is installed on the basis of the measured number of track crossings. |
