摘要：To form a disk substrate 42 having a no information area at low cost and without failure, a mold 12 is provided for forming a disk substrate 42 having a no information area 44. A cavity 32 of the mold 12 has a surface 50 corresponding to the no information area 44 and made of a mirror-surfaced plate 22. A cylindrical member (sleeve 35) is inserted in an inner hole 38 of the mirror-surfaced plate 22. An annular projection 33 is provided on the end surface of the cylindrical member adjacent to the cavity.
