摘要：
In a magnetic sheet recorder, a scraping member is mounted in association with a magnetic head to be put into contact with the magnetic layer of a magnetic sheet together with the magnetic head. The scraping member is mounted ahead of the head so as to treat the recording track of the magnetic sheet in advance of the head when the magnetic sheet is rotated. The scraping member removes from the surface of the magnetic layer scratches and dust particles which cause drop-out of the output level.
