    摘要: An active start judgment circuit is electrically connected to an AC/DC transforming power supply which has at least one standby power unit to transform AC to DC in regular conditions and a main power unit to transform the AC to the DC in an ON condition for operation of an electronic equipment. The start judgment circuit bridges the standby power unit and the main power unit, and generates a reference potential based on a voltage output from the standby power unit, and gets a power signal from the standby power unit to be compared with the reference potential to output a start signal to the main power unit to transform the AC to the DC. Thus the standby power unit can actively drive the main power unit to supply DC power to activate the electronic equipment.

    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.
