A rotary input apparatus is disclosed. A laser beam is directed onto a localized area of the metallic substrate coated with the interstitial element locally raising a temperature of the metallic substrate to a temperature causing the interstitial element to diffuse into the substrate. The seamless layer can be water or vapor impermeable or resistant so as to prevent microorganisms, pathogens, liquids, or other substances from passing through the sleeve. Moreover, the system and method is executed to permit modification of the streaming media playlist by the at least one user device. A bottom semiconductor die is disposed in the window of the interposer and interconnected to the top semiconductor die. The berms normally forming at the radial extremities of the pits and grooves in the masters, by thermal expulsion processes, may be reduced or eliminated by methods taught.
