A flat display comprises a flat tube (1) having a front panel (1F) and a back panel (1B) facing the front panel (1F), a fluorescent screen (2) formed on the inner surface of the front panel (1F) of the flat tube (1), an electron gun (10) disposed outside a region extending behind the fluorescent screen (2), a vertical deflecting electrode (3) disposed on the inner surface of the back panel (1B) and comprising a plurality of parallel electrode elements (3a) extending along the horizontal scanning direction, and an electrode structure (7) disposed between the vertical deflecting electrode (3) and the fluorescent screen (2), and comprising at least a counter electrode (4) constituting a vertical deflecting system together with the vertical deflecting electrode (3), a modulating electrode (5) and a horizontal deflecting electrode (6). The electron gun (10) has a back plate (41) and a cathode (1K) having a plurality of field emission cathode elements (K) arranged on a line on the inner surface of the back plate (41), and emits a flat electron beam (b) into the space between the vertical deflecting electrode (3) and the electrode structure (7). Since the flat electron beam (b) is produced by the plurality of field emission cathode elements (K) arranged on a line, the cathode (1K) of the electron gun (10) does not vibrate and hence the cathode (1K) can be formed in a large length suitable for a large display screen.

There are provided an optical disc (1) and an optical recording apparatus to form a tracking groove onto an optically recordable disc. This apparatus comprises a recording beam generator (2) to generate a recording beam such as a laser beam having a predetermined spot size so as to form a pattern of a predetermined width onto the disc; a light deflector (6) arranged on an optical path of the recording beam generator; and a driver (12) for driving the light deflector (6), for reciprocatingly moving the recording beam in a radial direction of the disc (1) at a high frequency, and for multi-exposing the disc (1) by the recording beam due to the movement of the recording beam in the radial direction, thereby a groove having a width wider than the pattern of the predetermined width is formed. With this apparatus, both of the discrete information pattern and a groove are formed by using a single recording beam. Namely, both of the pits and a wide groove can be formed by using a single recording spot.

摘要:
An optical disk recording apparatus, an optical disk recording method, an optical disk playback apparatus, and an optical disk playback method are provided. For example, the present invention is applied to a high-sound-quality optical disk (4, 6Z) which can be played back by a conventional compact disk player, and aims at supplying still higher-quality contents which can be played back even by a conventional optical disk apparatus. Second information (SC) is recorded by partial changes of optical characteristics, such changes being of such a degree which does not affect detection results of first and second areas which are detected by the irradiation of a laser beam (L2).
