Abstract (en)
[origin: WO9802880A1] A disc drive (10) includes a disc (30) and a motor having a rotatable portion (50) and a fixed portion (46). The fixed portion (46) and the rotatable portion (50) are separated by a bearing (52, 54), and the rotatable portion (50) supports the disc (30). A data transducer is coupled to an actuator (36) to move relative to the disc (30) to access different portions of the disc (30). The bearing (52, 54) includes a lubricant having an additive of perfluoropolyether with a reactive end group.
