| Zusammenfassung: | A disk unit has a voice coil motor to oscillate a suspension arm mounted at the leading end of a head with respect to a disk. The voice coil motor has a voice coil integrally attached to the tail end of the suspension arm, a magnet to cause a magnetic field to act on the voice coil, and a pair of yokes provided in such a positional relationship that the voice coil and magnet are sandwiched therebetween. At least one yoke has a roughly fan-shaped main body and a plate piece portion provided in a condition extended from one end side of the main body. After the formation of the main body and plate piece portion by press working, the yoke is formed by folding the plate piece portion on the main body. |
