Abstract :
Abstract—In high-speed magnetic surface recording devices such as disk memory and drum memory of digital computers, the read-out signal may be as low as 1 mV. If the read-out circuit is not properly designed, the signal-to-noise ratio could easily drop down to a level such that the digital information could not be reconstructed. It is, therefore, of vital importance that the data reconstruction circuits be designed to have high output for signal frequency while keepingminimum response to noise frequencies.
