摘要： An information storage disk holding member for holding an information storage disk in position in an information storage disk drive device, the holding member being made of glass-ceramics in which a crystal phase is dispersed in a glass matrix. The holding member has specific rigidity (Young's modulus/specific gravity) of not greater than 37 GPa, specific gravity of not greater than 3.0, coefficient of thermal expansion within a range from −50° C. to +70° C. which is within a range from +35×10−7/° C. to +130×10−7/° C., Young's modulus within a range from 95 GPa to 130 GPa, specific gravity within a range from 2.40 to 2.60 and bending strength within a range from 400 MPa to 800 MPa. There is provided an information storage disk holding member which is capable of coping with a high speed rotation of a disk in conformity with tendencies toward high speed transmission of information, increasing mechanical strength for adaptation to mobile uses, having a thermal expansion property matching that of other drive component parts and eliminating defects caused by solving out of alkali. There is also provided an information storage disk drive device using this holding member.
