PURPOSE:To provide a titled target which enables efficient production of a photomagnetic recording medium by embedding flaky bodies having paramagnetism in the prescribed positions of a base body which has ferromagnetism in the stage of a sputtering state. CONSTITUTION:Cylindrical flaky bodies 6 of about 5mm. diam. consisting of a rare earth element such as Gd, Tb, Dy or the like having paramagnetism in the stage of a sputtering state are embedded in the adequate positions of a plate-shaped body 5 having ferromagnetism in the stage of a sputtering state, thereby constituting a target for sputtering. The embedment of the bodies 6 into the body 5 is accomplished simply by forming preliminarily prescribed holes in the body 5 and fitting the bodies 6 into the holes. The high-speed mass production of a recording medium for magnetooptic recording element consisting particularly of the rare earth and transition metal alloy is made possible with good reproducibility by using such target. |
