Abstract: PURPOSE:To prevent any melting-out of platinum particles from a crucible or prevent mixing of platinum particles into molten material and get molten material of high quality by a method wherein a thin film oxide dispersion reinforcing platinum or oxide dispersion reinforcing platinum alloy is applied to an inner surface of a main body of the platinum crucible or platinum alloy crucible or both inner and outer surfaces of the crucible through a clad or a liner manner. CONSTITUTION:A cylindrical part 1' is made by a forming process from a clad plate member and by a welding operation at an edge part. A main body 7 of a crucible having the cylindrical part 1' and a comical part 3' is made of platinum or platinum alloy 8. Oxide dispersion reinforcing platinum of clad or a liner 9 of oxide dispersion reinforcing platinum alloy is applied to an inner side of the main body 7 of the crucible. In this way, the crucible 6' is a so-called double structure comprising a main body 7 of the crucible of platinum or platinum alloy and the inner liner 9 of oxide dispersion reinforcing platinum or oxide dispersion reinforcing platinum alloy. Due to this fact, a strength of the crucible 6' itself can be increased and a leakage of molten ferrite out of platinum particles can be prevented. It has a function of barrier with the dispersed oxide against the platinum particles.

When erasing is performed, with turning/inverting the permanent magnet 21 by 180 deg. against a disk plane, the north pole is faced with the plane of the disk D, and the polarity is inverted from S to N. In this state, with setting the power of the laser beam at almost same power as one in the recording and performing a continuous irradiation making the track of the disk D follow up, reverse directioned bias magnetic flux in a recording time is impressed on the disk D, and recorded information is erased. Therefore, the efficiency of the recording and the erasing at the inner and outer peripheries of the recording medium can be always held at a prescribed level.
