摘要： The present invention is aimed at providing a magnetic disk and a magnetic disk apparatus both of which have a high performance lubricating film which makes continuous sliding endurance and low adhesiveness compatible, and a lubricating film having a self repairing function which makes it possible to recombine scratched off lubricating agent from the magnetic disk surface by sliding with a head onto the magnetic disk surface. The lubricating film comprises at least two kinds of lubricating agents each of which forms an individual layer, the layers being laminated. An adhesion enhancing layer is formed between a magnetic film and a lubricating agent at the surface of the magnetic disk, and the adhesion enhancing layer is fixed onto the magnetic film surface. Then, the adhesion enhancing layer and the lubricating agent are combined. The adhesion enhancing layer and the lubricating agent form a salt or complex body, and the lubricating agent can repeat adsorption and desorption with the adhesion enhancing layer reversely by a thermal reaction.

摘要： A zoom lens system includes from the object side a first lens unit of positive refractive power and a second lens unit of negative refractive power. The zoom lens system further includes a rearmost lens unit on the most image side. During zooming from the shortest focal length condition to the longest focal length condition, the first lens unit is moved toward the object side so that the distance between the first and second lens units increases. During focusing to a shorter object distance condition, the first lens Unit .is moved toward the object side while the rearmost lens unit is moved toward the image side, and a ratio between movement amounts of the first and rearmost lens units varies according to zooming.

摘要： For an internal combustion engine with a supercharger, a slip of the driven wheel is controlled by reducing torque of the engine, when the extent of the slip becomes large in relation to a road surface. When the running status of the engine exists in a non-supercharging region, the slip is controlled by at least one of operations for reducing the amount of fuel to be supplied to the engine and for retarding the timing of ignition (first slip control). On the other hand, in a supercharging region, the slip is controlled by lowering the pressure to be supercharged (second slip control). In a transient period of time when the running status of the engine is caused to shift from the non-supercharging region to the supercharging region when the first slip control is being conducted in the non-supercharging region, the first slip control is allowed to be continued until the slip is caused to be converged, in place of the second slip control.

摘要： A reproduction-only magneto-optical disk has first and second magnetic layers. First micro areas .alpha..sub.0 where an exchange coupling force acts between the two magnetic layers, and second micro areas .alpha..sub.1 where no exchange coupling force acts between the two magnetic layers are formed in the disk. Either or both of the two kinds of micro areas serve as information units, and information is expressed by the presence/absence or length of the information units. The two magnetic layers are exchange-coupled to each other at a temperature not more than Curie Temperatures of the two layers, and directions of magnetization of the magnetic layers can be aligned at room temperature in a state wherein an interface magnetic wall is formed between the two magnetic layers in each first micro area. A disk reproduction method and a reproduction apparatus are also provided.
