Abstract
An information recording system comprising a read/write device including a read/write head for reading and writing information from and on a rotatable data-storage medium rotated by a first drive motor, and electrically operated elements such as a second drive motor for moving the read/write head relative to the data-storage medium, reading and writing amplifiers, and detectors for sensing operating conditions of the recording system such as the angular position of the data-storage medium. Electric power is supplied to such electrically operated elements from a power source via power disconnect switches connected between the power source and the respective electrically operated elements for selective power supply to the individual elements. The recording system further comprises a control device connected to the disconnect switches for controlling their operations in order to connect the power source to the respective elements only while the operation of the elements are required, and disconnect the elements from the power source when the operations of the elements are not required.
