MAGNETIC RECORDING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18164120 titled 'MAGNETIC RECORDING DEVICE
Simplified Explanation
The patent application describes a magnetic recording device with a magnetic head and a controller.
- The magnetic head consists of two magnetic poles, a magnetic element, and terminals connected to the magnetic element.
- The controller is connected to the magnetic element and a coil, and is responsible for the recording operation.
- During recording, the controller supplies a recording current to the coil and applies a voltage between the terminals of the magnetic element.
- When the applied voltage is changed while the recording current is supplied, the differential resistance of the magnetic element exhibits two distinct peaks at different voltages.
Original Abstract Submitted
According to one embodiment, a magnetic recording device includes a magnetic head and a controller. The magnetic head includes first and second magnetic poles, a magnetic element provided between the first magnetic pole and the second magnetic pole, first and second terminals electrically connected to one end and another end of the magnetic element, respectively, and a coil. The controller is electrically connected to the magnetic element and the coil, and performs a recording operation. In the recording operation, the controller supplies a recording current to the coil while applying an element voltage between the first and second terminals. When the applied voltage is changed while the recording current is supplied, a differential resistance of the magnetic element becomes a first differential resistance peak when the applied voltage is a first voltage, and becomes a second differential resistance peak when the applied voltage is a second voltage.
