Abstract

A write head of a magnetic storage device comprising a write tip comprising a magnetic material; a write pulse generator configured to generate a bias comprising a variation between the magnetic storage device and the write tip write pulse signal. The write pulse signal includes one or more write pulses effective to tunnel electrons from the write tip into the magnetic storage device. The dataflow generator is configured to provide a dataflow signal to the write tip, wherein the dataflow signal is operable to change the polarity of spins in the electrons from a first polarity to a second polarity.

Description

[0001] This application claims priority to US Provisional Patent Application Serial No. 61 / 566,885, filed December 5, 2011 and is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to magnetic storage devices, and more particularly to the use of electron tunneling for writing data to magnetic storage media. Background technique [0003] Magnetic storage devices are a critical link in the information technology industry. Early tape drives and hard drives are examples of magnetic storage devices. For hard disk drives, the data density of data bits written on magnetic media has increased by more than two million times since the first magnetic disk drives were applied to data storage. Additionally, read / write data rates associated with read / write heads used in magnetic disk drives continue to improve. While read heads can be scaled to smaller and smaller sensing areas, write head technology is becoming difficult to continue...
