A multicontact electrode array suitable for implantation in living tissue includes a distal end having multiple spaced-apart ring or band electrode contacts carried on a flexible tube carrier. Each ring electrode contact is laser welded to a respective wire tip that has a multi-helix orientation on the inside of a separation tube. The center of the multi-helix wire defines a lumen wherein a positioning stylet, or other suitable positioning tool, may be removably inserted when the electrode array is implanted. The method of making the multicontact electrode array includes, as an initial step, winding lead wires around a suitable mandrel so as to form a multi-helix configuration. (Alternatively, the wire may be purchased in a multiwire pre-wound configuration that defines a lumen, in which case the mandrel is slipped inside the lumen.) Then, at a distal end of the electrode, each wire within the multi-helix winding is unwound so as to protrude out from the winding. Next, a non-conductive separation silicone tube which has a longitudinal slit along its length, is placed around the wound wires. Ring contacts are then placed over the silicone tube at a distal end of the electrode array and spaced apart as desired. These ring contacts also have a slit therein through which the protruding wire ends may exit. The silicone tube is used as a spacer to centrally locate the multi-helix wound wires with the ring contacts. A compressive die may be used to hold the pre-assembled ring contact, multi-helix wire, separation tube in their desired positions, and may be used to close the opening or slit of each ring contact through which the wire tips protrude. The wire tips are then individually trimmed to a suitable distance. A laser welding process may then be used to bond each lead wire to a corresponding ring contact. Finally, the preassembled electrode array is placed in a molding die, and a polymer filler is injected into the internal gaps of the electrode array components.

Provision is made to perform a write trial process in a stable manner at all times in a write trial area for the purpose of determining optimum recording power. Sub-areas of the write trial area are used successively from an inner circumference side of the medium to an outer circumference side of the medium with respect to the spiral direction that extends from the outer circumference side of the medium to the inner circumference side of the medium, and the sub-areas of the write trial area are used successively from the outer circumference side of the medium to the inner circumference side of the medium with respect to the spiral direction that extends from the inner circumference side of the medium to the outer circumference side of the medium With this provision, the write trial process is performed by accessing a sub-area portion of interest without accessing the sub-area portion having undergone the write trial, no matter which record layer is used. Servo control and address read can thus be stabilized. As a result, a seek operation toward the sub-area of interest is also stabilized, thereby achieving a stable write trial process.

The invention provides techniques for reducing or altering the magnetic noise of an AC rotary electric machine. A magnetic noise reducing harmonic current of order n, whose frequency is n times the frequency of the fundamental frequency component of a polyphase AC current fed to an armature of a polyphase AC rotary electric machine, is superimposed on the polyphase AC current, thereby reducing or altering a harmonic component having a frequency (n−1) times the frequency of the fundamental frequency component and occurring due to a radial magnetic excitation force acting radially on an iron core of the AC rotary electric machine. Magnetic noise is caused by a vibration whose energy is the sum of the circumferential and radial vibrations of the iron core occurring due to the magnetomotive force of the rotor, and altering the radial vibration is particularly effective in altering the magnetic noise; as the harmonic component of the radially acting magnetic excitation force, occurring due to harmonic components having frequencies 3, 5, 7, and 13 times the fundamental frequency, has a frequency 6 or 12 times the fundamental frequency, the magnetomotive force of the rotor can be effectively reduced or altered when a current having a frequency 7 or 13 times the fundamental frequency is superimposed on the stator current.
