METHOD FOR DETERMINING DRIVING PULSE, CONTROLLER AND MAGNETIC STORAGE APPARATUS

摘要

Embodiments of the present invention provide a method for determining a driving pulse. The method comprises: sending an ith driving pulse to a magnetic storage track and a reading device, i being a natural number not equal to 0; determining whether the reading device reads data of a magnetic domain under the driving of the ith driving pulse; when it is determined that data of a magnetic domain is not read, sending an (i+1)th driving pulse to the magnetic storage track and the reading device, the driving strength of the (i+1)th driving pulse being increased based on the driving strength of the ith driving pulse by a first preset strength value; determining that data of a magnetic domain is read under the driving of the (i+1)th driving pulse; and determining the driving strength of the (i+1)th driving pulse to be the minimum driving strength of the magnetic domain. By means of the embodiments of the present invention, the minimum driving strength for driving the magnetic domain to move can be determined. The embodiments of the present invention also provide a controller and a magnetic storage apparatus.
