    • A slot-loading disc device is provided that, even if an ejection failure occurs due to contact between a disc and peripheral components, can eliminate the ejection failure. The slot-loading disc device (1) comprises: a conveying mechanism (9) for loading a disc (3) through a disc insertion opening (11) to a disc mount (7) and ejecting it from the disc mount (7) to the disc insertion opening (11); an ejection failure detector for detecting an ejection failure in which the ejection to be performed by the conveying mechanism (9) is prevented; and a conveyance controller for, when the ejection failure is detected, performing a back-and-forth control in which the disc (3) is moved back in a loading direction and then conveyed again in an ejection direction.
    • 提供了一种插槽加载盘装置,即使由于盘和周边部件之间的接触而发生喷射故障,也可以消除喷射故障。 插槽加载盘装置(1)包括:传送机构(9),用于通过盘插入口(11)将盘(3)装载到盘安装件(7)并将其从盘安装件(7)弹出到 盘插入口(11); 用于检测防止由输送机构(9)执行的喷射的喷射故障的喷射故障检测器; 以及传送控制器,当检测到喷射故障时,执行盘(3)沿加载方向移回并随后在喷射方向上再次传送的往复控制。

    • The present invention relates to an optical head device, an optical recording device, and an optical recording method, and an object of the present invention is to enable to acquire optimum recording characteristics of an optical recoding medium having multiple data layers, with respect to each of the multiple data layers without increasing learning time required for learning a relation between aberration amount and optimum recording compensation with respect to each of the multiple data layers. To accomplish this object, the optical head device, the optical recording device, and the optical recording method of the present invention are constructed such that the wavefront converting means 4 is driven in such a manner as to reduce the aberration amount detected by the aberration detecting means 12. The output controlling means 13 holds learned data as to the relation between the driving amount of the wavefront converting means 4 and the output of the light source 1, and controls the output of the light source 1 based on the driving amount of the wavefront converting means 4 and the learned data.
