摘要： According to one embodiment, a magnetic disk device includes a magnetic disk, a spindle motor, a magnetic head, a ramp load mechanism, a filter, and a control section. The control section rotates the spindle motor at a second rotating speed for a given period of time at startup of the device, and then loads the magnetic head from the ramp load mechanism to a prescribed position on the magnetic disk. The second rotating speed is higher than a first rotating speed at which the spindle motor is rotated at the magnetic head reads/writes data from/to the magnetic disk.

摘要： A phonograph player includes a body with a motor configured to drive a drive wheel and also having a head-shell. The head-shell rotates relative to the body and holds a needle cartridge. The head-shell is also configured to activate a sensor governing motor speed. The sensor is calibrated for rotation of the head-shell to alter motor speed, and such that rotating the head-shell results in the body portion maintaining a constant RPM relative to the phonograph. The sensor may be a light sensor, and the apparatus may include a head-shell clip for holding the head-shell. Preferably, the head-shell holds the needle cartridge in a trailing configuration, and a housing at least partially cover the body.

摘要： The present disclosure relates to a system and methods of controlling a system of storage devices. In particular, the present disclosure relates to methods of controlling peak power and energy consumption in storage systems due to storage devices while maintaining data availability. The system implements a method for maintaining data availability in a storage subsystem by determining a plurality of storage devices to include in a fixed set of storage devices based on a fault tolerance system. The storage devices included in the fixed set are prevented from transitioning between RPM spin modes. The method further involves controlling peak power and energy consumed by the storage subsystem which may include transitioning the storage devices not included in the fixed set from a high RPM operational mode to a low RPM operational mode to reduce peak power and energy consumption.

摘要： An optical recording method and apparatus with different recording rates are provided for effectively increasing the average recording rate. The optical recording method includes the steps of: controlling a recording rate with a constant linear velocity (CLV) control mode; recording data; judging whether the recording rate has to be increased according to a rotating speed of a spindle motor or a recording position; and performing a process for changing the rotating speed if the recording rate is increased, and continuing recording data at the same recording rate if the recording rate is not increased. The step for changing the rotating speed includes the steps of: pausing recording data; registering a paused zone of a disc; determining a new rotating speed of the spindle motor, and driving the spindle motor at the new rotating speed; and linking recording zones to continue recording data at a new recording rate from the paused zone, when the rotating speed of the spindle motor is stable. Consequently, the invention can optimize the overall average recording rate by effectively utilizing the maximum rotating speed of the spindle motor in conjunction with the maximum recording rate.
