PROBLEM TO BE SOLVED: To provide a rotary disk-fixing sheet co-possessing the properties, such as flexibility and coefficient of friction, considered to be necessary for the rotary disk-fixing sheet and the high dimensional accuracy in a thickness direction by applying a rubber raw material to a structure reinforcing film configurating a base material by using various kinds of coaters and to provide a method for manufacturing the same. SOLUTION: The fixing sheet of, for example, an annular shape capable of freely attachably and detachably fixing the recording disk to a spindle of a disk drive unit for the rotary disk consists of the structure reinforcing film 12 of the required thickness configurating the base material and the rubber layer 14 of the required thickness consisting of liquid rubber applicable by using various kinds of the coaters on the films 12 as its raw material. The rubber layer 14 is so formed that the dimensional accuracy of its final thickness is kept within±10μm. COPYRIGHT: (C)2004,JPO
