Title: Innovations by DetHau Wu
Introduction
DetHau Wu is a notable inventor based in Singapore, recognized for his contributions to technology and engineering. He has been granted 3 patents that showcase his innovative approach to solving complex problems in the field of data storage and processing.
Latest Patents
One of his latest patents is focused on fly height compensation using a read gain control loop. This invention involves apparatus and methods that regulate the head fly height to compensate for variations in the height of a disk surface. An exemplary apparatus includes a circuit that detects disk height variation in response to changes in the gain of a variable gain amplifier within an automatic gain control loop. This circuit amplifies a read signal as the head reads from the disk surface and regulates the head fly height to compensate for the detected variation in disk height.
Another significant patent by DetHau Wu involves the calculation of data frequencies in recording media. This computer process establishes data frequencies for recording data in zones of a zone bit recording medium in a disc drive. The process identifies at least three data points for each zone, correlating data frequencies with corresponding bit error rates. It calculates the slope of a curve between each two data points, averages the slopes, and determines the data frequency based on the average slope. If the difference between the average and default slopes exceeds a first threshold value, or if the spread of the slopes exceeds a second threshold value, the data frequency is calculated based on both the average and default slopes.
