Abstract: Provided is a fan unit that includes: a plurality of fans (3) arrayed in a direction intersecting an air blowing direction; printed circuit board (4) to which the plurality of fans (3) are electrically connected; chassis (5) having back portion (5a) with which surfaces (3a) of the plurality of fans (3) orthogonal to the air blowing direction are engaged and bottom portion (5b) supporting the plurality of fans (3), in which printed circuit board (4) is disposed; and bracket (6) having fixing portion (6c) fixed to bottom portion (5b) of chassis (5) by screws and configured to sandwich the plurality of fans (3) engaged with back portion (5a) of chassis (5) in cooperation with back portion (5a).

Abstract: A reproduction apparatus is designed to select and decode speech and subtitles (characters) in a given language from a disk on which various types of information are recorded in different languages. This system arrangement makes it possible to standardize the manufacture of disks and reproduction apparatuses world-wide, resulting in a reduction in production cost. In a disk 100, various types of information are recorded in different languages along with video information. A reproduction apparatus selects information in a given language from the reproduced information using a data string processing section 203, a system control section 204, and an operator section 205, and supplies the selected pieces of information to each of a video processing section 206, a subtitle decoder 211, and an audio processing section 213.

Abstract: Recorded at high density on an optical disk are at least one title set and a volume information file. The title set consists of a plurality of files aligned on a boundary between logical sectors. The files store title set management information and data objects to be reproduced. To retrieve data from the optical disk, volume file information is read out, thereby acquiring information about the desired title set. Then, the information for indicating steps or reproducing the data object and managing the desired title set is acquired. Using the title set management information, data is reproduced from the optical disk.

Abstract: In reproduction of a predetermined title recorded on an optical disk, when multiangle video images are recorded on the optical disk, an angle mark having a form of a camera is turned on. During reproduction of this title, when reproduction reaches a multiangle video image recorded portion, the angle mark flashes so that a viewer or user of the video can be notified of a state in which video reproduction at an angle different from that of the currently reproduced video image is possible.

Abstract: A multi-scene recording disk and a data reproducing apparatus which enables a user to select and enjoy one of simultaneously proceeding scenes, and also enables a program editor to edit programs using a new concept and novel fashion. Related program movements, each consisting of program bars, are recorded on the disk 100. The data reproducing apparatus includes a data string processing section 203, a system control section 204, an operator panel 205, a video processing section 206, and audio processing sections 211 and 213. The sections 203 and 204 and the panel 205 select any one of the program movements and switch one movement to another, and select any one of the program bars of the movement selected and to switch one movement to one bar to another. The information thus selected is supplied to the video processing section 206 and the audio processing sections 211 and 213.

Abstract: An optical disk comprises at least one video title set where data is to be recorded, and a video manager for recording management information for managing the video title set. The video title set includes VTSTT.sub.-- VOBS where data is recorded, VTSM.sub.-- VOBS where at least one video title set menu, which is to be used at the time of checking and selecting contents of various kinds of data recorded in the VTSTT.sub.-- VOBS, and corresponds to the contents, is recorded, and VTSM.sub.-- PGCI.sub.-- UT where the recording position of the video title set menu in this VTSM VOBS is recorded for the content of each data corresponding the video title set menu. The video manager comprises VMGM.sub.-- VOBS where a video manager menu corresponding to the management information is recorded and VMGM.sub.-- PGCI.sub.-- UT where the recording position of the video manager menu in this VMGM.sub.-- VOBS is recorded for the content of each data corresponding to the video manager menu.
