Optical recording/reproducing device having a controller for reducing vibrational noise during recording by slowing moving speed of pickup |
摘要 |
An apparatus for recording and/or reproducing a disk-shaped optical recording medium such as a magneto-optical disk includes recording and/or reproducing unit, a moving unit and a controller. The recording and/or reproducing unit records input information on the disk-shaped optical recording medium loaded on the apparatus and reads out information recorded on the optical recording medium. The moving unit moves the recording and/or reproducing unit in the radius direction of the disk-shaped optical recording medium. The controller controls a recording and/or reproducing operation of the recording and/or reproducing unit and an operation of the moving unit. The controller controls the moving unit such that a moving speed for moving the recording and/or reproducing unit by the moving unit when the recording and/or reproducing unit records input information on the disk-shaped optical recording medium is lowered as compared with a moving speed for moving the recording and/or reproducing unit by the moving unit when the recording and/or reproducing unit reproduces the disk-shaped optical recording medium.
