ABSTRACT:
A magnetic recording apparatus using a rotatable magnetic disc as a recording medium, includes a composite magnetic head having integrated erase (E1 & E2) and read/write gaps (R/W-1 & R/W-2) separated from each other in a longitudinal direction of a recording track on said magnetic disc to erase and record/reproduce data with respect to said magnetic disc, said composite magnetic head being arranged for carrying out 2-field image recording with respect to a pair of adjacent tracks on said magnetic disc. A double record instructing device (62, 64, 29, 30) is provided for generating a double record instructing signal in response to an operation of a user and a controller (17, 19, 20, 25, 26) is provided for controlling a head driving sequence (FIG. 12) in response to a double record instructing signal for carrying out a double recording operation, by erasing one of an image data of a pair of image data of adjacent tracks and then recording another image data on the erased track.
