摘要： A display device includes a screen to form an intermediate image with light; a concave mirror, and a first mirror disposed between the screen and the concave mirror. The first mirror includes a first reflective area to reflect the light emitted from the screen to the concave mirror; a second reflective area to reflect the light emitted from the concave mirror to an area where a virtual image is formed; and a common reflective area in which the first reflective area and the second reflective area at least partly overlap on each other.

摘要： In a tilt correction method, first information about a specific inclination of an object lens is acquired in response to an access request to an information recording medium. The specific inclination is obtained when the signal characteristic of a push-pull signal becomes a prescribed level in or near a target access area. Then, second information about the optimum inclination of the object lens is acquired for the target access area, based on the first information and tilt difference information representing a difference between a first inclination and a second inclination of the object lens defined in advance in a particular area on the information recording medium. The first inclination corresponds to an optimum reproduced signal from the particular area, and the second inclination is obtained when the signal characteristic of the push-pull signal from the particular area becomes the prescribed level. Finally, tilt correction information is estimated from the second information.

摘要： An optical disk device and a tilt correction method capable of high precision tilt correction with a smaller number of measurement positions are provided. Prior to data recording and reproduction, a number of measurement positions are set in the radial direction on an optical disk with intervals between two adjacent measurement positions shorter and shorter from the inner region to the peripheral region of the optical disk. The tilt at each of the measurement positions is measured, and the resulting tilt data are stored in a memory. The tilt data are used for making tilt corrections when recording or reproducing data on the optical disk.
