Method for adjusting position of magnetic head

Abstract

Abstract PURPOSE:To adjust the position of a magnetic head with high efficiency by driving a magnetic recording medium through a record head and then a reproduction head together with application of recording signals to both heads respectively and then developing the images on the recording medium produced by both heads. CONSTITUTION:The recording signal for test, for example, is supplied to a record head 1 and at the same time a DC power supply 5 such as a dry cell, etc. is connected to a reproduction head 2 for supply of power. Under such conditions, a recording medium 3 is driven toward an arrow head to form images produced by both heads 1 and 2 on a recording surface. Then the medium 3 is dipped into a nonvolatile liquid containing the magnetic iron powder to develop each latent recorded image. The relative positions of both heads 1 and 2 can be simply recognized from the visible images TW and RW recorded on the medium 3. Thus it is possible to decide whether or not both heads are set at correct positions respectively.
