摘要:
A high density thermal recording and magnetic reading recording medium and system combines near-field optical recording and the sensitive reading technique of the magneto-resistive head to overcome the restriction of optical diffraction limitation to increase the density of the recording medium. It mainly has sub-micro cylindrical lenses directly formed on the substrate of the recording medium to enable a near-field optical laser to write and generate smaller optical spots thereby to achieve smaller recording bits and increase the recording density.
摘要:
A DC power system is provided to generate the power from renewable energy and directly supplies the DC power to DC household appliances, thus saving energy that would be wasted during the conversion of DC to AC and back to DC and saving the cost of a rectifier or power factor corrector. The DC power system includes a generator, a DC/DC converter, a battery bank, a bi-directional inverter, a DC load and a controller.

摘要:
A manufacturing method for a far-infrared (FIR) substrate is provided. The manufacturing method includes steps of providing a substrate and sputtering a FIR emission material onto at least one surface of the substrate to form a thin film.
摘要:
The present invention includes that using single layer amorphous CoTbAg thin films as heat assisted magnetic recording (HAMR) media, and the method for producing these CoTbAg amorphous thin films. Co69.48−XTb30.52AgX films with x=0˜25.68 at. % are fabricated by DC or RF magnetron sputtering and rotating substrate. Two kinds of targets can be used. One is the CoTbAg alloy target. The other one consists of Co, Tb and Ag three targets. The CoTbAg film is prepared by co-sputtering of Co, Tb and Ag targets. The film composition can be controlled by changing the sputtering power density of each target. CoTbAg films are deposited on glass substrate or nature-oxide silicon wafer at room temperature. These films have high saturation magnetization and high perpendicular coercivity. They have amorphous structure and can be applied to HAMR media.
