摘要： A data storage system and device is provided in which parasitic capacitance between multiple preamplifiers and a signal channel is minimized. Multiple read signals from multiple data heads are amplified by corresponding ones of the multiple preamplifiers. A connection device coupled to each of the multiple preamplifiers selectively electrically couples the amplified read signal from the active preamplifier to the signal channel, while electrically isolating the amplified read signals from the inactive preamplifiers from the signal channel. In addition, a method of coupling multiple preamplifiers to a signal channel is provided.

摘要： The present invention provides a method and storage device for reducing the occurrence of data miscompare errors. The method includes identifying a destination track as either an even track or an odd track and selecting a pseudo-random set of data based on this identification. The pseudo-random set of data is combined with write data to produce randomized data that is used as the basis for a write signal to be written to the destination track.
摘要翻译：本发明提供一种用于减少数据错误比较错误的发生的方法和存储装置。该方法包括将目的地轨道识别为偶数轨道或奇数轨道，并且基于该识别来选择伪随机数据集合。伪随机数据集合与写入数据组合以产生随机化数据，该随机数据被用作要写入目的地轨道的写入信号的基础。

摘要： A magnetic disc storage system includes a magnetic storage disc and a transducing head. During periods of inactivity the transducing head is dithered whereby the head is moved to tracks on the disc according to a number of criteria. The criteria includes wear reduction, power reduction, avoidance of textured zones, head cycling, increased fly height and clearing of debris carried on the head.
