摘要： A method and circuit to stop a spindle motor in the absence of the external supply voltage in which the spindle motor is structured to move a hard disk provided with at least one reading or writing head moved by a voice coil motor, the spindle motor provided with a plurality of coils. The method includes rectifying the backelectromotive force of the spindle motor to produce a braking current, driving the voice coil motor with at least a portion of the braking current until the speed of the spindle motor becomes lower than a predetermined stop speed, and, after the parking of the at least one reading or writing head of the voice coil motor, stopping the spindle motor by short-circuiting the coils of the spindle motor.

摘要： Some embodiments of the invention are directed to a data storage system that includes a disk and solid-state non-volatile memory (NVM). During a power failure, the data storage system may use back EMF (BEMF) voltage from the spindle motor of the disk to park the heads of the disk and/or store data in the NVM. In one embodiment, a demand regulation circuit regulates loads that use voltage generated from the BEMF. The demand regulation circuit may be used to selectively cause a controller to adjust the rate of programming to the NVM in order to reduce the load. For example, the demand regulation circuit may assert a throttle signal to the controller upon detecting that the voltage generated from the BEMF is below a certain threshold. Programming rate may be throttled, programming cycles may be staggered, and/or programming time may be lengthened. Throttling may enable the use of smaller circuitry.
摘要翻译：本发明的一些实施例涉及包括盘和固态非易失性存储器（NVM）的数据存储系统。在电源故障期间，数据存储系统可以使用来自磁盘的主轴电机的反电动势（BEMF）电压来停放磁盘头和/或将数据存储在NVM中。在一个实施例中，需求调节电路调节使用从BEMF产生的电压的负载。可以使用需求调节电路来选择性地使控制器调整对NVM的编程速率，以便减少负载。例如，当检测到从BEMF产生的电压低于某个阈值时，需求调节电路可以向控制器断言油门信号。编程速率可能会被限制，编程周期可能会交错，和/或编程时间可能会延长。节流可以使用更小的电路。

摘要： An optical disk drive includes a spindle motor, a power source, a microprocessor, and a comparator. The spindle motor is for supporting a disk. The power source supplies a first voltage to drive the spindle motor to rotate. The microprocessor signals the power source to supply a second voltage to slow down rotational speed of the spindle motor when receiving a power-off signal. The comparator compares the rotational speed with a predetermined value. The microprocessor signals the power source to stop supplying power to the spindle motor when the rotational speed is smaller than the predetermined value. A controlling method for controlling the spindle motor in the optical disk driver is also provided.

摘要： Arrangements and methods for implementing a “spin-down policy” for HDD motors that is “smart”, flexible and admirably achieves an objective of ensuring prolonged motor life as just discussed. To this end, one specific implementation involves (among other things) the addition of a dedicated cache that acts as a buffer element of sorts for writing or obtaining data during a period when a motor may be spun down, especially (but not necessarily exclusively) in instances when a notebook needs to be running for a large portion of the day. Other analogous implementations are of course possible that would achieve similar ends.

摘要： A method and apparatus are provided for automatically setting a signal processing mode for reproduction of video signals read from a disc, such as an optical disc, to a selected signal processing mode, such as one of, for example, NTSC and PAL modes, in a disc apparatus, such as an optical disc apparatus, for example, a DVD player, internally equipped with a tuner adapted to receive broadcast signals. In accordance with the method and apparatus, it is possible to automatically set the signal processing mode for reproduction of video signals in a disc apparatus, by referring to video mode set data stored in the disc apparatus and a type of broadcast signals received through a receiver unit, such as a tuner, such that the signal processing mode corresponds to the mode of a display device, such as an external monitor or TV, connected to the disc apparatus. Accordingly, it is unnecessary for the user to manually set the signal processing mode of the disc apparatus.

摘要： PURPOSE: A method for setting a reproduced video signal processing method in an optical disk device having a tuner is provided to set a signal processing method of a reproduced video to one of NTSC and PAL systems, to set the signal processing method of the reproduced video to be identical with that of an outer monitor or a TV set, thereby removing a manual operation. CONSTITUTION: When a system is powered on(S10), a microcomputer reads video mode setup data(S11). The microcomputer receives a TV broadcasting signal, and detects whether a signal processing method of the TV broadcasting signal is an NTSC system or a PAL system(S12), then compares with a value of the video mode setup data(S13). If the signal processing method is the NTSC system and the value has the PAL system, the microcomputer confirms whether the value has been updated by a user(S15). If not, the microcomputer updates the value to an NTSC system value(S16).

摘要： PURPOSE: A method for controlling a disk stop in an optical disk device is provided to calculate a time for applying a brake voltage to stop a disk in reference to a brake voltage apply time by playback position and a brake voltage apply time by rotation reduction ratio, and to apply the brake voltage at the calculated time, thereby exactly stopping the disk. CONSTITUTION: When an optical disk is inserted(S10), a servo controller enables a motor driver to apply a driving voltage to a spindle motor to rotate an optical disk at high speed. A sled motor performs a series of initial servo operations(S11). If a user wants to stop a playback operation, the servo controller sets a disk rotation stop mode(S12), and detects a rotational angle speed of the disk(S13). The servo controller reduces a current spindle linear velocity(S14), calculates a time for applying a brake voltage, and applies the brake voltage to the spindle motor at the calculated time(S16). The servo controller continuously monitors whether the disk stops(S17).
