Abstract: An optical disk device records recording data transmitted from a host device onto an optical disk. Then, as a process for checking the recorded data, the optical disk device reproduces the data from the optical disk to perform a Verify process in a recording quality determination unit, while transmitting the reproduced data to the host device. The host device performs a Compare process to compare the reproduced data transmitted from the optical disk device with the recording data transmitted to the optical disk device. At least if it is determined to be poor quality as a result of the Verify process by the recording quality determination unit or if it is determined that the data do not match as a result of the Compare process by the host device, the corresponding data is alternately recorded in an alternate area of the optical disk.

Abstract: A data archive system comprises a plurality of library apparatuses, a buffer which stores data temporarily and a server which controls the library apparatuses and the buffer. If the data is stored in the buffer, the library apparatus records the data to optical disc(s). In the first controlling state, the buffer stores the data input to the system from the outside, even if at least one library apparatus is powered off. Accordingly, the service to the user for archiving data in the state of offline is provided because it is possible to record and read new data to/from the buffer even if the power source of a library apparatus which is part of a group is turned off.

Abstract: A virtual image display device includes: an image projection device that projects an image light; a diverging element on which the image light emitted from the image projection device is incident, spreading the image light out over a range of a predetermined angle; and a light branching element that reflects the image light emitted from the diverging element, while transmitting the incident light from the surface other than the reflecting surface. The image light from the image projection device is formed into an image on the diverging element. A virtual image of the image formed on the diverging element is generated on an extension line in the opposite direction to the emission direction of the image light reflected from the light branching element. Further, an optical axis converting element is provided to convert the optical axis of the image light emitted from the image projection device, into a predetermined direction.

Abstract: For an optical device as a transmission-type scanning optical microscope having a pinhole or a slit for limiting the amount of a detected light beam, a method of moving a scanning beam without moving an observation sample to be scanned is realized. A scanning beam from a beam scanning mechanism that has passed through an observation sample is focused onto a reflection plate, and is then returned back again to the observation sample. A light beam that has returned back from the sample is further fed back to the beam scanning mechanism, and then, the light beam that has been limited through a fixed pinhole or a slit is detected with a photodetector.

Abstract: In a hologram recording/reproducing apparatus where a wavelength-variable laser diode having the external resonator structure is used as its light-source, stable recording/reproducing quality is ensured with respect to a change in the recording/reproducing wavelength against the expansion or contraction of a hologram medium caused by the hologram recording and the temperature change. When the output wavelength from the wavelength-variable laser diode is changed to a predetermined target wavelength, the temperature of the laser light-emission part of the wavelength-variable laser diode is controlled by a temperature control element so that the wavelength band, within which the light-emission power of the laser light-emission spectrum is higher than a predetermined light-emission power, includes the above-described predetermined target wavelength.

Abstract: The white balance for a high brightness region and a low brightness region is improved in an image display device using MEMS and a laser light source. An image processing unit of the device superposes a signal based on a first measured value of a light quantity at a first temperature on a picture signal, during its blanking period, which is supplied to the laser light source, and superposes a high frequency signal on the picture signal during its effective scanning period. An amplification factor of the light source drive unit is changed so that a second measured value at a second temperature comes close to the first measured value at the first temperature as a target value based on the second measured value at which the light quantity of light generated at the laser light source is measured at the second temperature different from the first temperature on the signal based on the first measured value. By superposition of the high frequency signal, white balance control in a low brightness region for which control is especially difficult is performed with adequate accuracy.
