Abstract

756,131. Sound records. DANIEL, K., [trading at TEFI-APPARATEBAU DR DANIEL KOMM.-GES.]. Oct. 15, 1954 [Oct. 16, 1953], No. 29809/54. Drawings to Specification. Class 40(2) An endless band-shaped sound carrier in the form of a roll has one face of the band prepared in a manner to reduce adhesion between the convolutions and wherein a lubricant is incorporated which continuously exudes in small quantities. In the embodiment described, the band is provided with a raised dot or screened surface on the remote side from that containing the sound track, and in such surface is incorporated metal soaps such as calcium stearate, cadmium stearate, barium stearate or mixtures of such. The band may have a magnetic record surface or have an engraved sound track for use with a stylus.
