Method of making magnetic read/write head/flexure/conductor unit(s)

A method of making on a supporting substrate plural, read/write structural units each for use in conjunction the reading and writing of information with respect to a relatively moving recording medium, said method comprising

• preparing, on a surface in said substrate, an etchable layer,
• forming on said etchable layer, with appropriate staging, and by a deposition process, plural, side-by-side-adjacent, dielectric unit bodies, one set of surfaces of which rest on said etchable layer, and whose respective lateral dimensions are defined by etchable, wall-like stripes that extend on the layer between, and separate, adjacent bodies, with said stripes being etchable under the same circumstances that said etchable layer is etchable, and
• following said preparing and forming steps, etching said etchable layer and said stripes to free individual bodies from the substrate.

A method of making on a supporting substrate a read/write structural unit for use in conjunction with the reading and writing of information with respect to a relatively moving recording medium, said method comprising

• preparing, on a surface in said substrate, an etchable layer,
• forming on said etchable layer, with appropriate staging, and by a deposition process, a dielectric unit body having the desired lateral dimensions, and
• following said preparing and forming steps, etching said etchable layer to free the body from the substrate.

A method of making plural, read/write structural units each for use in conjunction with the reading and writing of information with respect to a relatively moving recording medium, said method comprising

• forming, with appropriate staging, and by a deposition process, plural, side-by-side-adjacent, dielectric unit bodies whose respective lateral dimensions are defined by etchable wall-like stripes that extend between and separate adjacent bodies, and
• following said forming step, etching said etchable stripes as a step toward freeing individual unit bodies.

A method of making on a supporting, substantially planar substrate, a read/write structural unit adapted for integration with other components for use in conjunction with the reading and writing of information with respect to a relatively moving magnetic recording medium, said method comprising

• forming on a first planar surface in said substrate, by a deposition process, and with appropriate staging, a dielectric unit body, and during said forming, creating within said body, with staging related to that associated with said forming step, and also by a deposition process, magnetic yoke structure, and an electrical coil and conductor means operatively associated with said yoke structure,
• exposing a surface of said body and yoke structure in a newly formed second planar surface which is generally orthogonal to said first planar surface, and
• fabricating on said second planar surface, by a deposition process, a pole structure magnetically coupled to and operatively associated with said yoke structure.
