MAGNETIC HEAD AND MAGNETIC RECORDING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240296865 titled 'MAGNETIC HEAD AND MAGNETIC RECORDING DEVICE

The abstract describes a magnetic head with specific voltage characteristics during a recording operation.

The magnetic head includes a first and second magnetic pole, with a magnetic element between them.
The magnetic element consists of five magnetic layers, exhibiting differential electric resistance when the voltage changes.
The voltage between the magnetic poles results in two positive peaks, with the second peak voltage higher than the first.
During recording, an element voltage higher than the second positive peak voltage is applied between the magnetic poles.

Potential Applications: - Data storage devices - Magnetic recording systems - Magnetic sensors

Problems Solved: - Enhanced recording performance - Improved data storage efficiency

Benefits: - Higher recording quality - Increased data storage capacity - Enhanced magnetic sensing capabilities

Questions about Magnetic Head Technology: 1. How does the differential electric resistance of the magnetic element impact recording operations? 2. What advantages does the higher second positive peak voltage offer in terms of data storage performance?

Original Abstract Submitted

according to one embodiment, a magnetic head includes a first magnetic pole, a second magnetic pole, and a magnetic element provided between the first and the second magnetic poles. the magnetic element includes first to fifth magnetic layers. a differential electric resistance of the magnetic element when a voltage between the first magnetic pole and the second magnetic pole being changed includes a first positive peak and a second positive peak. the voltage corresponding to the first positive peak is a first positive peak voltage. the voltage corresponding to the second positive peak is a second positive peak voltage. the second positive peak voltage is higher than the first positive peak voltage. an element voltage applied between the first magnetic pole and the second magnetic pole in a recording operation is higher than the second positive peak voltage.
