A Technology to Visually Detect Hard Disk Record Information
Jincai Chen · Microprocessors · 2007
A technology to visually detect hard disk record information is proposed.This technology first makes an exactly location on the specified track,collects original electromagnetic signal which hasn't been processed by head's reading/writing channel,through the test points on hard disk's control circuit,processes the data with a data filter algorithm,deduces the magnetic distributing intensity data from the electromagnetic data according to the relative electromagnetic formula,then presents the magnetic intensity data in a image form real-timely,by this way,the visual detection to the hard disk's recording information was achieved.
