A radial tracking method for an optical information carrier format with non-uniformly spaced tracks is disclosed, wherein a plurality of tracks are spaced apart at a track pitch TP2, respectively, within a broad spiral having a track pitch TP, in an information layer of an optical information carrier. A consolidated hard material may be produced using hard particles such as B4C or carbides or borides of W, Ti, Mo, Nb, V, Hf, Ta, Zr, and Cr in combination with an iron-based, nickel-based, nickel and iron-based, iron and cobalt-based, aluminum-based, copper-based, magnesium-based, or titanium-based alloy for the binder material. The receptacle body is applied to a first portion of the connector assembly, and the locking sleeve is applied to a second portion of the connector assembly.
