Abstract:
A process for the production of an assembly having several magnetic heads, comprising the steps of:forming on a first substrate at least one first subassembly by forming at least two first pole pieces, separated by a first gap,forming on a second substrate at least one second subassembly, by forming at least two second pole pieces separated by a second gap and by forming at least two magnetic connectors made from a magnetic material, said magnetic connectors being placed alongside two of said second pole pieces,reversing and engaging one of the substrates on the other in such a way that said two magnetic connectors of said second substrate come or almost come into contact with said two first pole pieces of said first substrate so as to ensure a magnetic continuity,thinning out said second substrate until said second pole pieces and said magnetic connectors appear or almost appear,forming on said thinned out second substrate a first magnetic circuit connecting said two magnetic connectors and a first reading and/or writing means magnetically coupled to said first circuit, andforming a second magnetic circuit connecting said two second pole pieces and a second reading and/or writing means magnetically coupled to said second magnetic circuit.
