Abstract
A write circuit for facilitating a write head for writing to a memory in a computer is described. The write circuit includes a supply voltage source configured to provide current to the write circuit. The write circuit further includes a current source coupled to the supply voltage source, the current source configured to maintain the current at a predetermined value. The write circuit further includes a switch coupled to the current source, the switch being configured to bypass the current source during a time when the current is changing.
