Abstract
A ported vacuum drum (20, 56-98) is provided on its exterior cylindrical surface (22) with one or more lengths (24) of a master magnetic recording medium supported by bands (102) of elastomeric material in position to contact a layer (14) of slave magnetic recording medium provided on one side and along at least one edge of a web (10); so that, vacuum applied (74-82) between the cylindrical surface and the web at locations (88-94) spaced from the zone of contact (98) between the recording media will hold the slave layer on the web securely in contact with the length of master magnetic recording medium on the drum as the drum rotates, thereby permitting anhysteretic recording from the master to the slave. A method of anhysteretically recording is taught.
