摘要： A motor includes a rotor magnet, driving coils and the detecting wire elements. The rotor magnet is mounted on a rotor yoke and has a plurality of magnetic pole pairs arranged at equal angular spacings, each having north and south poles. At least one pair of is unequally magnetized so that the north and south poles thereof are of unequal strength. The other magnetic pole pairs are equally magnetized so that the north and south poles thereof are of equal strength. The driving coils are provided on a stator yoke opposite from the rotor magnet. The detecting wire elements are provided on the stator yoke. The detecting wire elements are arranged at an angular spacing substantially equal to that of the magnetic pole pairs of the rotor magnet. The detecting wire elements generate output signals when the rotor yoke comprising the rotor magnet rotates to cause the unequally magnetized magnetic pole pair to move across from the detecting wire elements.

摘要： A rotary type reproducing apparatus for reproducing a recorded signal through the tracing of many recording tracks formed at a predetermined pitch on a record bearing medium, one after another, includes a moving apparatus for moving the record bearing medium in a direction which crosses the recording tracks; a shifting apparatus for shifting the rotary head in a direction which crosses the rotation plane thereof; an apparatus for forming a first pulse signal in association with the record bearing meduim moving action of the moving apparatus; an apparatus for forming, on the basis of the first pulse signal, a second pulse signal which is of a higher frequency than the first pulse signal; a counting apparatus for counting the pulses of the second pulse signal; and a control apparatus for forming, on the basis of the counter value of the counting apparatus, a control signal which controls the shifting apparatus. Arranged as such, the shifting apparatus shifts the rotary head using a control signal which is in close proximity to an ideally analogously varying control signal, so that the recording tracks on the medium may be accurately traced.
