Abstract
1439076 Contact-copying of magnetic tape recordings MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 17 Sept 1973 [21 Dec 1972 29 Dec 1972] 43607/73 Heading G5R A recorded master tape 3 and an unrecorded slave tape 4 are wound, Fig. 7, from respective supply reels 1, 2 on to a take-up reel 18 with their magnetic surfaces in contact, and contactcopying is effected by the application of a transfer field from a generator 24 during rewinding, Fig. 8, of the tapes from the take-up reel 18 to their respective supply reels. As shown, the generator 24 is slidably mounted so as to be movable under solenoid action from behind to in front of a tape-guide surface 21, Fig. 5. The generator 24 may apply an erasing field to the slave tape 4 during winding, Fig. 7.
