An electrolytic reactor including a conical recess of removable slices through which the electrolyte circulates towards a part to be coated under the action of a pump setting up forced circulation. The part is polarized to act as a cathode, facing a coaxial anode in the recess. This configuration leads to good electrolyte flow in front of the part, allowing accelerated deposit with a uniform thickness of the coating material, and dimensions of the chamber may be added.

A process for producing a double magnetic head with two head gaps with opposite azimuths by forming a first magnetic head with a first head gap having a predetermined inclination angle on a first substrate and a second magnetic head having a second head gap with a second inclination angle on a second substrate and etching a first recess along the first head. The second head is received in the first recess and a second recess is etched along the second head to receive the first head. Subsequently, one of the heads is reversed and the first head is fitted into the second recess and the second head into the first recess so that the first and second inclination angles are opposed in a common reference frame thereby providing opposite azimuth angles.

A flight slider for magnetic recording. The slider according to the invention has at least one indentation to the rear of the relief or reliefs and the slider has utility for magnetic recording. The slider includes a support structure and at least one rail carried by the support structure, the rail defining a face which faces toward the recording medium, the rail having a front part and a rear part relative to the direction of motion of a moving recording medium. The head is located at the rear part of the at least one rail and the at least one rail has an indentation around its entire periphery.

A polishing machine having a taut microabrasive sheet. The machine includes a machine polishing disk in the form of a planar reference disk and a microabrasive sheet held taut on the disk by an appropriate mechanism. The mechanism for holding the microabrasive sheet taut can be a delivery roll and a receiving roll. The machine can be applied to the polishing of silicon wafers containing integrated components and in particular magnetic read-write heads.

Polishing machine with an improved sample holding table in which the table has a cardan system with two first shafts having a first common longitudinal axis and two second shafts having a second common longitudinal axis. The shaft axes being in a polishing plane and intersecting in the center of the sample face to be polished. The machine can be applied to the production of magnetic read-write heads.
