摘要： A hydrodynamic spindle motor including an internally disposed heating element in a stationary spindle portion having a spindle hub rotatably coupled thereto. The hydrodynamic spindle motor has particular application for supporting discs for co-rotation for a disc drive. The heating element is activated to control viscosity of a hydrodynamic fluid of a hydrodynamic bearing rotationally supporting the spindle hub relative to the stationary spindle. Operation of the heating element reduces viscosity of the hydrodynamic fluid to reduce motor power requirements and improve “up-to-speed” time.

摘要： An information handling system, such as a disk drive, includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a load spring and a slider attached to said load spring. A ramp is also attached to the base near the disk stack. The ramp is used to load and unload the sliders to and from the disk. The slider and load spring are attached to form a gimballing connection between the slider and the load spring. The disk drive also includes a spindle motor and spindle motor controller for rotating the disk at a first rotational velocity and for rotating the disk at a second rotational velocity. The slider includes an air bearing surface. Landing pads, made of a durable material such as diamond like carbon, are formed on the air bearing surface of the slider. A method for loading a slider from a ramp to a disk surface includes rotating the disk at a first rotational velocity, as the slider is loaded. The disk is rotated at a second rotational velocity after the slider is positioned over the disk. The first rotational velocity is slower than the second rotational velocity so that damage due to contact between the disk and slider is minimized.

摘要： An automatic balance device for disk includes rolling beads of different sizes and a magnetic piece within the turntable or clamping chassis of the CD-ROM driver. The rolling beads of different sizes will be released from the magnetic piece at different rotating speeds of the disk. Therefore, the rolling beads with larger weight are first released from the magnetic piece and then bumped by the rolling beads with smaller weight, which are released from the magnetic piece at a later time. The rolling beads with larger weight can be moved to a desired position to counteract the imbalance force of the disk.

摘要： A disk player having a self-compensating dynamic balancer which can limit internal vibrations generated by an eccentric center of gravity of a disk, and a turntable, a clamper and a spindle motor which incorporate a self-compensating dynamic balancer. The self-compensating dynamic balancer is formed integrally with rotating members in a disk player; that is, a turntable, a clamper and/or a rotor of a spindle motor. The self-compensating dynamic balancer includes at least one race which is integrally formed with the rotating member and rotates around a rotational shaft, a mobile unit which is located in the race to be capable of moving, and a cover member for covering an opening of the race. Thus, internal vibrations occurring due to the eccentric center of gravity of the disk can be effectively limited by the self-compensating dynamic balancer in which the mobile unit is disposed far away from the center of orbital rotation by a centrifugal force during rotation of the disk.

摘要： A spindle motor inclination angle adjusting mechanism in an optical disk apparatus including a spindle motor. The spindle motor is mounted on a motor base (122) in such a manner as to be tiltable in a direction around a second tilt movement axis. The motor base is mounted on a chassis in such a manner as to be tiltable in a direction around a first tilt movement axis. The spindle motor is urged in the directions around the first and second tilt movement axes by a leaf spring. By turning adjuster screws, the spindle motor is moved backward against the resilient force of the spring, thereby effecting adjustment of the inclination angle thereof in the directions around the first and second tilt movement axes independently.
