Abstract
A non-contact detection head which compensates for variation and the spacing between a detection head and a circular recording medium. The recording medium has a magnetized pattern recorded along the periphery thereof, and is mounted on a central rotary shaft. A detection head is spaced from and faces the recorded pattern on the recording medium and generates an output as a function of the recorded pattern. In one embodiment, pneumatic means is provided for preventing fluctuations in the clearance between the recording medium and the detection head from influencing the output of the detection head. In a second embodiment, a mechanical arrangement is provided to achieve this result. In a third embodiment, an electrical circuit is provided to compensate for fluctuations in the clearance between the recording medium and the detection head.
