摘要： Ultraviolet rays are radiated over a lubricant film formed on the surface of a recording medium such as a hard disk. The recording medium is then subjected to exposure to a bases. The radiation of the ultraviolet rays allows the lubricant film to uniformly spread over the surface of the recording medium. The repellency can be enhanced over the surface of the recording medium. The friction can be reduced on the recording medium. Moreover, when the recording medium is exposed to the base, organic acid existing on the surface of the recording medium and/or in the lubricant film can be transformed into salt. The organic acid can be washed off or removed from the surface of the recording medium and/or out of the lubricant film in this manner. Less organic acid greatly contributes to prevention of generation of corrosion mounds on the recording medium over a longer period.

摘要： Control data is stored in a first memory. Control data inputted from an external device is stored a second rewritable memory. A control section selects either one of the first and second memories and controls operation according to a control program using the control data stored in the memory selected. An image corresponding to control data is displayed on a display screen. Through the image, it is possible to select particular control data from a plurality of control data. The control data selected via the screen is sent to the second memory. Processing can be therefore executed to appropriately cope with requirements of the user.

摘要： After a sacrifice layer 51 has been formed on a substrate 50, there are formed a protective layer 41, flying surface layer 42, head element layer 43 and actuator layer 44. Further, a slider body 45 is formed by means of plating, and then the sacrifice layer 51 is removed so that the slider body can be separated from the substrate 50. In the thus obtained magnetic head slider 40, when an actuator 40a is loaded or unloaded, a frictional force, generated when the head element 43 is made to come close to or contact with a recording medium, is reduced and the head element 43 can accurately follow a track on the recording medium. A portion of the head element layer 43 forms at least one protrusion 46 which protrudes from a surface opposed to the recording medium onto the recording medium side.

摘要： In a virtual sound source localization apparatus, a distance between two loudspeakers and a shortest distance between a line connecting the loudspeakers and a listening position are set beforehand, and a listener operates an operating section to localize a Cch sound source at an approximately center of the loudspeakers, thereby adjusting a sound balance of the loudspeakers. In addition, a controller calculates a difference in distance from the loudspeakers to the listening position, sets a delay amount of delay correctors such that sound emitted from the loudspeakers substantially reaches the listening position simultaneously, and adjusts sound output timing of the loudspeakers. In this way, even though the listening position is changed, the listener can operate the operating section to optimize a virtual surround effect.
