ABSTRACT:
An apparatus for determining the position and/or orientation of a transducing head positioned on one side of and close to a rotating transparent-core magnetic storage disk. Light is introduced into the disk to establish total internal reflection therein. A detector disposed on the other side of the disk opposite the head detects the intensity of light on the interior region of the disk. The detected intensity is representative of the separation of the head from the disk.
