Abstract

1,200,971. Recording-apparatus. O.E. STœRZINGER. Jan.9, 1968 [Jan.11, 1967], No.1347/68. Heading G1J. Recording-apparatus comprises a recording- arm 5 which is moved in accordance with a variable by a transducer 6 and which has a permanently magnetic point 9 in contact with a magnetizable foil 1 moving in a direction substantially perpendicular to the direction of movement of the arm 5, a portion of the resulting magnetic trace being made visible by a "magnetic tape viewer" 4. The foil may be in the form of an endless band, Fig. 4 (not shown) or it may be in disc form either stiff in itself or carried by a non-magnetic stiff carrier. The arm 5 may be reciprocated rectilinearly or arcuately and a permanent magnet 8 may be provided to erase the trace. The viewer 4 is essentially a flat container closed on the top by a glass disc and carrying a very thin membrane. It is filled with a liquid suspension of iron oxide particles having a grain size and chemical composition as those used in making magnetic tapes or foil.
