摘要： Magnetic reference patterns may be generated on a disk or other magnetic media without the need for seed wedges. This involves writing a first magnetic reference pattern to the disk with a servo writer. The disk may then be transferred to a hard disk drive. Control circuitry within the hard disk drive may recognize the first magnetic reference pattern and then position a RW head within the hard disk drive based on the first magnetic reference pattern. As the RW drive is accurately positioned based on the first magnetic reference pattern a second magnetic reference pattern may be written to the disk using the RW head. The RW head location is determined based on the velocity and phase between the read-write head and spiral sync marks contained within the first magnetic reference pattern.

摘要： A method for switching signals using one of a plurality of mirrors in an array structure. The method includes determining an optical path to be formed between an input fiber and an output fiber. The method also includes determining a set of mirrors to be used to form the optical path. The set of mirrors includes at least a first mirror. The first mirror is coupled to a mechanical spring assembly and an actuation assembly. The method captures an analog signal indicative of a spatial position of the first mirror using a position sensing device. The sensing device is coupled to the mirror. The method also converts the signal analog signal into a digital signal. The method processes the digital signal indicative of the spatial position of the mirror using the digital signal processing device to obtain a characteristic of the mirror. The method provides a control signal based upon the characteristic of the mirror. The converts the control signal into an analog control signal. The method uses the analog control signal with the actuation assembly to set a desired position of the first mirror.

摘要： Embodiments of the present invention significantly reduce the number and complexity of processing operations to be performed. This is done by receiving the learned run out or vector A to be rotated by phase q. This phase q may be limited to a π/4 resolution. Sine function values and cosine function values based on q are selected from a group of values comprising −1, 0, and +1. The sine function values and cosine function values selected may then be applied to the learned run out or vector A to rotate the vector A by phase q. Because the sine and cosine values are limited to −1, 0 and +1 many multiplication processing operations are eliminated. This greatly simplifies the processing requirements associated with phase rotating of this learned run out.
