Latest Patents

One of Mukai's latest patents is for an "Automatic gain control for magnetic disk-drive preamplifier." This invention includes a preamplifier system designed for magnetic disk-drives. The system features a read amplifier that generates a read signal corresponding to data read from a magnetic disk via a magneto-resistive (MR) read head. Additionally, it comprises a gain control amplifier that amplifies the read signal based on a digital gain value, producing an amplified read signal. A feed-forward automatic gain controller (AGC) is also included, which sets the digital gain value based on the amplitude of the read signal.

Another notable patent is for "Methods and apparatus to monitor and control hard-disk head position." This invention describes methods and apparatus for monitoring and controlling the position of the hard-disk drive head. In one example, a hard-disk drive system includes a platter and a read head configured to read information from the platter. The head position controller receives a signal via the read head and determines if the distance between the platter and the read head is less than a predetermined distance. Based on this determination, the temperature of the read head can be varied.
