PURPOSE:To adhere stably a sheet and a deleting head and to delete a recording without fail by inclining and installing a deleting head a little to the outer circumference side for the magnetic sheet and pushing down the head with a pad. CONSTITUTION:An inner circumference side upper end part 2a of a deleting head 2 is located at the position evacuated a little from a sheet 1 and an outer circumference side upper end part 2b is further located at the position. An extention line (l) of the upper end part ridgeline of a head 2 intersects at a point A between a sheet hub outer circumference part 3a and a sheet innermost circumference track and like that, the heat is installed a little in inclination. Consequently, when the head is pushed down with a pad 4, a cross section of the sheet 1 goes to be a straight line. In this way, the sheet 1 is stably adhered with the deleting head 2 and the recording of the sheet 1 can be deleted without fail. |
