ABSTRACT:
A rotary magnetic media scanner for magnetic media player-recorders having a plurality of disk elements where each element is arranged in a simple disk configurations to facilitate manufacture. The disk elements are comprised of high magnetic permeable material and a low magnetic permeable material. The regions made of high magnetic permeable material define magnetic paths which generally have either axial or radial symmetry. Each of the elements form a portion of a complete magnetic circuit. When each of the elements are stacked together, they form a complete magnetic path operable for delivering a magnetic signal read from a tape medium to an electrical transducer and further to an amplifier circuit.
