Abstract

This paper presents recent works on experimental evaluation of the writing process induced EMI/EMC to the reading process in a magnetic recording system. Both the time domain and frequency domain methods have been applied. The EMI/EMC effects due to the writing process with high current have been studied within the frequency range of 30 MHz to 1 GHz, and found to be frequency dependent. The observed information is essential for implementation of two-dimensional magnetic recording technique (TDMR), in order to achieve a higher data capacity and data access in future storage system.
