Introduction:

Norman S. Blessum, based in Thousand Oaks, CA, is a notable inventor with an impressive portfolio of nine patents to his name. His work has significantly impacted the field of disk drive control systems, particularly through advancements in detection and amplification circuits.

Latest Patents:

One of Blessum's latest patents is for a detection and amplification circuit designed for a disk drive control system. This system incorporates innovative servo sectors written onto a disk, where each sector consists of three sets of marker pulses. These pulses are arranged such that three adjacent marker pulses span two tracks and include high-frequency sinusoidal signals. The effectiveness of the servo control relies on the amplitudes of the pulses sensed by the read/write head while traversing a servo sector. The system further comprises an amplifier to rectify and amplify these high-frequency signals, alongside a sample-and-hold circuit that retains at least three values representative of the amplified signals. Additionally, the integration of synchronizing means ensures accurate sampling of pulse amplitudes within the servo sector. His invention also involves a multiplexing circuit that sequentially provides multiplexed signals reflecting the sampled values.

Another significant contribution from Blessum is the development of techniques and associated apparatus for a magnetic disk transducing system. This groundbreaking approach enables recording along spiral tracks in a unique Herringbone pattern, utilizing a pair of orthogonal skew gaps that operate in tandem.
