A method for selectively printing different messages on labels printed by an in-store scale involves providing an in-store scale including a label printing mechanism with a supply of labels and a communications link for receiving information from a site external to the store. The mounting system also includes a second powertrain mount that exhibits a second gradual rate of change of static stiffness when under load. The method may further include forming a second servo pattern on a segment of a second track of a second layer of the recording medium. A method of diffusing hydrogen into fused silica and a fused silica article loaded with hydrogen formed by the method are also described.
