摘要： An apparatus and method for writing a product information code (PIC) to a head-disc assembly (HDA) of a disc drive data handling system to facilitate subsequent identification of the HDA. The PIC is configured as a sequence of n multi-bit encoded words. Servo data are written to a disc of the HDA as a number of p angularly spaced apart servo data fields, the servo data used by a servo control circuit to effect head positional control. The n encoded words are distributed across a subset n of the p servo data fields so that the n encoded words replace at least a portion of the servo data in the n servo data fields. Preferably, the n encoded words are written to Gray code (track address) fields of the n servo data fields and are provided with error detection and correction capabilities.

摘要： A motor control circuit for controlling rotation of a motor includes parallel first and second controller paths (gears). Each path includes a proportional and integral (PI) controller and a digital to analog converter (DAC). The DACs operate over different dynamic ranges (gains). The respective PI controllers have different control parameters to provide a common frequency response. The first controller path is used to output motor control signals to control the application of drive current to the motor. The circuit switches to the second controller path once the first controller path operates within a selected tolerance of a minimum or maximum level of the first dynamic range. The final state of the first PI controller is used to configure the initial state of the second PI controller to eliminate transients. The use of different gears allows the circuit to adaptively accommodate large variations in motor current and spindle motor configurations.
摘要翻译：用于控制电动机的旋转的电动机控制电路包括平行的第一和第二控制器路径（齿轮）。每个路径包括比例和积分（PI）控制器和数模转换器（DAC）。 DAC在不同的动态范围（增益）下运行。相应的PI控制器具有不同的控制参数以提供共同的频率响应。第一个控制器路径用于输出电机控制信号，以控制对电机的驱动电流的应用。一旦第一控制器路径在所选择的第一动态范围的最小或最大水平的公差内运行，则电路切换到第二控制器路径。第一个PI控制器的最终状态用于配置第二个PI控制器的初始状态，以消除瞬变。使用不同的齿轮允许电路自适应地适应电机电流和主轴电机配置的大变化。
