    摘要： Methods relating to compensating a pre-defined seek profile for use in a data storage device, such as a disc drive, to manage the internal temperature of the device are disclosed. One embodiment disclosed is related to determining a seek profile compensation value that can be used to compensate the pre-defined seek profile for temperature. Another embodiment is a method of using a seek profile compensation value during device operation to maintain the data storage device operating temperature below an operating temperature threshold. Yet another embodiment of the present invention may be thought of as a controller for a data storage device. The controller comprises a microprocessor having a pre-determined seek profile and a means for compensating the pre-determined seek profile based on a current operating temperature.

    摘要： One way to minimize full DC head-skew re-calibrations rendered necessary by changes in storage media drive operating temperature is to compensate for temperature-induced DC head-skew using a known relationship between temperature-induced DC head-skew and storage media operating temperature. More specifically, a first DC head-skew is measured at a first arbitrary temperature of the storage media drive. A second DC head-skew is measured at a second arbitrary temperature of the storage media drive. A DC head-skew correction factor is calculated using the first and second DC head-skews at the first and second arbitrary temperatures. When a multi-head storage media drive is powered-up for operation, a temperature sensor located in the storage media drive assembly measures the current storage media drive temperature. The head-skew correction factor is applied based on the measured temperature to correct the DC head-skew.

    摘要翻译： 通过存储介质驱动器工作温度的变化使必要的全直流磁头偏移重新校准最小化的一种方法是使用温度引起的直流磁头偏移和存储介质工作温度之间的已知关系来补偿温度引起的直流磁头偏移 。 更具体地，在存储介质驱动器的第一任意温度下测量第一DC头偏移。 在存储介质驱动器的第二任意温度下测量第二DC头偏移。 使用第一和第二任意温度下的第一和第二DC头偏差来计算直流偏移校正系数。 当多头存储介质驱动器上电运行时，位于存储介质驱动器组件中的温度传感器测量当前的存储介质驱动器温度。 基于测量的温度应用头偏斜校正因子以校正DC头偏移。

    摘要： A shock detection circuit housed in an electronic device includes an output shock signal that is indicative of vibration amplitude. To compensate for vibrations that are experienced by the electronic device, the output shock signal is analyzed. The analysis of the output shock signal allows a vibration frequency of the output shock signal to be identified and used in vibration compensation.

    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.
