  • Disc drive having a preamplifier multiplexer
    Patent number: 6400520
    Abstract: 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.
