  • Patent number: 11770037
    Abstract: A motor includes a rotor configured to rotate with a shaft. The rotor includes a plurality of yoke portions and a plurality of holding portions each corresponding to a space portion provided between the adjacent yoke portions and configured to hold therein a magnet. At least one of the plurality of yoke portions includes a tab portion extending towards the holding portion and configured to hold the magnet held in the holding portion. The holding portion includes an insertion space provided between a first end portion of the yoke portion in an axial direction of the shaft and the tab portion. The insertion space allows the magnet to be inserted into the insertion space towards an inner side in a radial direction of the shaft.

  • Patent number: 5297330
    Abstract: Method of producing a core slider for a rigid magnetic disk drive, including a slider body having air bearing portions, and a core chip which has a magnetic gap for writing and reading information and which is integrally secured to the slider body. The slider body consists of a ferrite section which includes at least the air bearing portions and which is formed of Mn--Zn ferrite, and a non-magnetic ceramic section formed of a non-magnetic ceramic material. The core chip is accommodated in a groove formed in the slider body and bonded to the slider body by a glass material.
