Abstract
A pivoting, passive servo controlled, self propelled and tangentially tracking tone arm, featuring a floating head shell/transducer assembly that tracks the groove in a disk-record independently of the tone arm itself and utilizing the so-called inward force to propel the tone arm across the disk record.
Claims8
A tone arm for disk record players having a first end and a second end, being designed for motion parallel to a play back plane, said play back plane being parallel to a grooved side of a disk record, comprising in combination:
- a) pivot means at said first end of said tone arm for rotation in said play back plane,
- b) cam follower means also at said first end of said tone arm, sharing a coaxial relationship with said pivot means,
- c) stationary cam means, being in constant contact with said cam follower means, for controlled rotation of said tone arm parallel to said play back plane,
- d) carrying means for carrying said tone arm, said pivot means and said cam follower means from a point distal, relative to a center of said disk record, to a point proximal, relative to said center of said disk record,
- e) cradle means at said second end of said tone arm,
- f) a floating head shell, supported by said cradle means, for motion parallel to said play back plane, said floating head shell incorporating attachment means for mounting a transducer cartridge thereto.
