A method whereby the angle of attack formed by a slider acting as a floating magnetic head with respect to a magnetic member can be adjusted. The method includes selecting a speed of rotation of a magnetic member which is lower than the speed of rotation for normal operation of the member while the apparatus is in operation, rotating the member at approximately the preselected lower speed of rotation, and adjusting the angle of attack of the slider so that the slider will begin to float in the air approximately at the preselected lower speed of rotation.

To suppress light leakage at the time of dark state, and to provide a liquid crystal display device whose electrodes in the reflection areas can be formed with high precision. The liquid crystal display device has a reflection area within a pixel unit by corresponding at least to a reflection plate forming part, and the reflection area is driven with a lateral electric field mode and normally-white. A driving electrode for forming an electric field to a liquid crystal layer of the reflection area is formed on the reflection plate via an insulating film by using a non-transparent electric conductor.
