Abstract: An apparatus including an encoder scale disc and a mount, the encoder scale disc including radially and/or tangentially resilient features located radially outwards of a scale configured to interact with the mount so as to locate the scale disc on the mount. The encoder scale disc may include radially resilient features which may deviate radially from the disc. A method of manufacturing an apparatus including an encoder scale disc, including mounting a disc including radially resilient features to a device, wherein the radially resilient features of the disc interact with the device to place the disc in radial compression, mounting the disc on an apparatus, wherein mounting features on the device and the apparatus interact in the same manner to place the disc in radial compression.
