    • The present invention provides a display device of high brightness which can eliminate brightness irregularities on a display surface while preventing the degradation of display quality attributed to an undesired electric field generated at the time of performing inverter driving of the cold cathode fluorescent lamps of a backlight. In a liquid crystal display device, a plurality of cold cathode fluorescent lamps of a backlight unit is arranged along a short axis of the display device. The cold cathode fluorescent lamp has a high-voltage electrode thereof connected to an inverter circuit and a ground electrode thereof connected to a ground. Further, the plurality of cold cathode fluorescent lamps arranged along the short axis have electrodes thereof arranged alternately between the high-voltage electrode and the ground electrode. a first side electrode of the first cold cathode fluorescent lamp connects to an inverter circuit on a first printed circuit board and a second side electrode of the first cold cathode fluorescent lamp connects to a ground;

    • A method for controlling head loading/unloading operations in a magnetic disk drive apparatus that can perform a head retracting operation by using a reserve power source in order to retract head elements to a predetermined rest position even when a primary power source has shut down during the operation of the apparatus has been developed. In order to guarantee proper power off unloading of head elements at a shutdown time of the primary power source, a system within the magnetic disk apparatus judges, prior to start the head loading control, whether a sufficient electric power is secured in a reserve system in order to retract the head elements to a predetermined rest position if a shutdown of the power source occurs.
