description PROBLEM TO BE SOLVED: To provide a magnetic erasing head device which can decrease the number of parts of a rotary head device and also can reduce the size of the rotary head device in the direction of rotary axis of a rotary cylinder. SOLUTION: This erasing head device includes a magnetic erasing head chip 2, an attachment plate 10 which supports the chip 2 and is fixed to a rotary cylinder 28 that is revolved by a drive source, a terminal plate 12 which is fixed to the plate 10 and relays the coil 8 to a rotary transformer 34 that is fixed to the cylinder 28 and a chip capacitor 23 which is connected in parallel to the coil 8 and constructs a resonance circuit with the coil 8. The plate 12 has a positioning hole 12a where a capacitor 23 is inserted at a position opposite to the transformer 34, and a solder land part 24 is formed at the fringe part of the hole 12a for connecting the capacitor 23 to the coil 8.
