Latest Patents

One of his latest patents is titled "Arrangement for reading information from a record carrier." This invention includes a read head, an amplifier for amplifying the signal read by the read head, an equalizer for equalizing the signal, and a bit detector for detecting bits in the signal. The arrangement also features a DC correction unit that subtracts a correction value from an input signal based on an error signal, resulting in a DC corrected output signal. The bit detector then detects a sequence of bits based on this corrected output signal. Additionally, an error signal generating unit is included to generate the error signal in response to the corrected output signal and the detected sequence.

Another significant patent is the "Device for write compensation in magnetic-media recording." This device is designed for write precompensation of data signals to be recorded on a magnetic medium. It has an input for receiving data signals and an output for supplying the signals to be recorded. The device delays a plurality of signal transitions in the output data signals compared to the input data signals. The signal path includes a series arrangement of a filter circuit and a hysteresis circuit, which allows for the influence of preceding symbol values on the transition to be recorded.
