IPC: G11B15/02
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To detect the presence/absence of magnetic data and to prevent at least a double exposed frame and an unexposed frame even when the influence of an electromagnetic noise is exerted. SOLUTION: A position detection part 12 detects the position of the perforation of a film 2 and discriminates which the area where a magnetic head 3 slides and contacts on, of a recording area adjacent to an exposed frame or a recording inhibition area adjacent to a space between the adjacent exposed frames. Then, a threshold setting circuit 10 sets a threshold for discriminating the presence/absence of the magnetic data based on an output obtained when the detection part 12 discriminates that the magnetic head 3 slides and contacts on the recording inhibition area. When the detection part 12 discriminates that the magnetic head 3 slides and contacts on the recording area, a decision circuit 11 compares the output from the magnetic head 3 with the threshold and discriminates whether or not the magnetic data is recorded in the recording area.  Then, the propriety of the actuation of the magnetic head 3 is decided in accordance with the output from the decision circuit 11.
