    • An optical disk apparatus includes an optical disk drive including an optical disk and an optical head, a power source for supplying electric power to the optical disk drive an apparatus casing for enclosing at least the optical disk drive and the power source, and a first air feed member having a first air passage. The first air feed member includes a first air inlet for introducing cooling air into the apparatus casing from outside of the apparatus casing so as to cool the optical disk drive, and an air filter disposed upstream of the optical disk drive in the first air passage such that the cooling air flows into the optical disk drive through the air filter. A second air feed member has a second air passage and included a second air inlet for introducing cooling air into the apparatus casing from outside of the apparatus casing so as to cool at least the power source. A partition member is provided for separating the first and second air passages from each other. The flow rate of the cooling air in the first air passage is set to such a value as to maintain the optical disk drive at a predetermined temperature or less such that the optical disk drive is not polluted with airborne dust.
    • 一种光盘装置,包括:光盘驱动器,包括光盘和光头;光源,用于向光盘驱动器提供用于至少包围光盘驱动器和电源的装置壳体;以及第一空气 进料构件具有第一空气通道。 第一空气供给部件包括:第一空气入口,用于从设备外壳的外部将冷却空气引入设备外壳,以便冷却光盘驱动器;以及空气过滤器,其设置在第一空气通道中的光盘驱动器的上游, 冷却空气通过空气过滤器流入光盘驱动器。 第二空气供给构件具有第二空气通道,并且包括第二空气入口,用于将冷却空气从设备外壳的外部引入设备外壳,以便至少冷却电源。 设置有用于将第一和第二空气通道彼此分开的分隔构件。 将第一空气通道中的冷却空气的流量设定为将光盘驱动器维持在预定温度以下的值,使得光盘驱动器不被空气尘埃污染。

    • This invention relates to tracking control apparatus for a recording disc reproducing apparatus in which recorded information is successively reproduced from a disc-like recording medium, which is rotated and driven, by way of a pickup means, and the invention provides a tracking control apparatus which is hardly affected by disturbance, such as vibrations, without deteriorating information-track-tracking characteristics of the pickup means by feeding back a detected output corresponding to a displacement of the pickup means from a reference position, to a first servo loop which controls the pickup means so as to scan along an information track to be reproduced using a tracking signal corresponding to a relative position between the pickup means and the information track.
