摘要： A video camera with a disk drive capable of recording and reproducing operations with stability and silence achieved by suppressing vibration and noise caused by disk rotation. The number of revolutions of the disk is controlled according to states of the video camera. The disk drive comprises a disk rotation control unit for rotating the disk at an optional number of revolutions under rotation control and an adjusting process unit for recording data on the disk, in which one or both of the disk rotation speed and the rotation control method are changed by using an adjusting process executed in a period when recording is performed and the adjusting process executed in a period when recording is not performed.
