With the Z-axis given as a central axis, on an XY-plane, arranged are a rigid force receiving ring, a flexible detection ring inside thereof, and a cylindrical fixed assistant body further inside thereof. Two fixing points on the detection ring are fixed to a supporting substrate, and two exertion points are connected to the force receiving ring via connection members. When force and moment are exerted on the force receiving ring, with the supporting substrate fixed, the detection ring undergoes elastic deformation. Capacitance elements or others are used to measure distances between measurement points and the fixed assistant body and distances between the measurement points and the supporting substrate. Elastic deformation of the detection ring is recognized for mode and magnitude, thereby detecting a direction and magnitude of force or moment which is exerted.

A method of manufacturing a multiplayer optical recording medium by depositing two recording layers, with a spacer layer sandwiched therebetween, on a substrate. The method includes using a rubber chuck which can undergo elastic deformation at least in radial directions to close a central mounting hole of the substrate to thereby fix the substrate having the recording layer formed thereon on a turntable. After a coating liquid for forming the spacer layer is dropped in the vicinity of a boundary portion between a peripheral surface of the rubber chuck and the substrate, the rubber chuck is caused to chuck a stamper for forming the first recording layer thereon while allowing the stamper to be placed over the substrate. Thereafter, the turntable is rotated to spin-coat the coating liquid. This makes it possible to form a spacer layer having a uniform layer thickness while preventing intrusion of air bubbles, without leading to high manufacturing costs.
