Abstract
PURPOSE:To eliminate the need of a means to move an external magnetic field impressing means near a medium or to move the means away the medium, by providing a magnetic flux inducing member consisting of a high permeable substance at one part of the titled cartridge main body, and intensively impressing the magnetic flux from the external magnetic field through the member to the medium. CONSTITUTION:A magnetic flux concentrating member 12 here consists of 'Permalloy(R)' (high permeable material) with an approximately triangular cross section, and two members 12 approximate to a magneto-optical recording medium 20 and are arranged so as to sandwich the recording medium 20 in upper and lower directions. Since the magnetic flux inducing member 12 consisting of the high permeable material is provided at one part of a cartridge main body 11, the magnetic flux from the external magnetic field impressing means is not diffused, is induced by the member 12, and as the result, even when the external magnetic flux impressing means is far separated from a medium 20 surface, magnetic force to reach the medium 20 surface is increased. Thus, without making the external magnetic area impressing means approach the cartridge by opening one part of the cartridge, the sufficient magnetic area can be impressed to the medium 20.
