Abstract

A magnetic transfer device enables precise positioning of both disks while preventing generation of dust by sliding of a holder, and also secures a space for transfer magnet arrangement. A master disk on which is formed a magnetic signal pattern and a magnetic disk which is to receive transfer are accommodated and brought into close contact in opposition to each other within an interior space formed by a male-side holder which moves to approach and withdraw and a female-side holder. A plurality of positioning pins are brought into contact with the outer face of the male-side holder to position the male-side holder, and by installing the positioning pins at positions lower than both the master disk and the magnetic disk, dust generated by sliding of the positioning pins does not fall onto the face of the master disk or the magnetic disk.
