SYSTEM FOR REPRODUCING MECHANICALLY STORED SIGNALS INCLUDING CARRIER HAVING DEFORMABLE MEANS COACTING WITH PRESSURE-SENSITIVE PICKUP MEANS

摘要

Apparatus for reproducing a mechanically recorded signal which includes a storage element and a signal pickup device. The signal is mechanically recorded on the storage element by means of a series of deformations in the surface thereof. According to the invention, the pickup device is arranged to apply a compressive force against these deformations and to sense the variations in this compressive force resulting from relative motion between the pickup device and the surface of the storage element.
