A transducer head for flexible disk applications is described providing a flat transducing surface depressed within a stabilizing ring which stabilizes the motion of the disk over the head. Manufacture is by bonding the stabilizer onto a central post incorporating a magnetic or optical transducer and lapping stabilizer to the required tolerance. Figs. 1 and 2 show sections through typical assemblies having a central flat topped transducer element. The transducer may be a read/ write element for magnetic recording or a plano front element of a lens assembly for optical recording by laser. The central flat surface is surrounded by and slightly below a stabilizing ring. The stabilizer is toroidal (Fig. 1) or flat topped (Fig. 2).
