Abstract

A rotating scan device for use with magnetic storage media, including a rotor, multiple magnetic transducers on the rotor with suitable gaps and orientations for writing or reading electronically modulated signals directly to or from magnetic storage media. The transducers scan in a helical fashion and include video and audio heads. There are means on the rotor for receiving and amplifying the signals read by the magnetic transducers. The rotor has means on it for transferring the amplified read signals from the rotating device. The rotor also has means for receiving write signals, as well as means for driving the magnetic transducers with the write signals. Means are provided for transferring power to the amplifying, transferring, receiving and driving means. Analog switch means are located on the rotor for connecting one of the multiple video head signals to the transferring means, and the analog switch means has a control input. Logic select means are also located on the rotor, connected to the control input, for selecting which of the multiple video head signals is connected to the transferring means; and there are means for transferring the logic select signal to the rotating device.
