Abstract :
The use of tunneling magneto-resistive (TuMR) head, at low temperature, has bad read/write characteristics for the disk regions with high data transfer rate. To prevent the bit error rates (BERs) degradation at low temperature, a solution which can quickly increase temperature more than specific value is proposed. A random seeking method with heater is operated to rapidly increase the rising speed of internal temperature and the weak writing/reading problems is solved.
