    • An information medium apparatus for performing at least one of a recording operation and a reproduction operation for the information medium, includes: a determination section for determining whether or not a cartridge for accommodating the information medium has been previously opened; and a control section for performing a start processing procedure corresponding to the information medium. When it is determined that the cartridge has not been previously opened, the control section performs a first start processing procedure for starting the information medium by using a blue laser. When it is determined that the cartridge has been previously opened, the control section determines whether or not the information medium is an information medium for which a start processing procedure is to be performed by using a laser other than the blue laser.
    • 一种用于执行信息介质的记录操作和再现操作中的至少一个的信息介质设备,包括:确定部分,用于确定用于容纳信息介质的盒是否已经被预先打开; 以及用于执行与信息介质相对应的开始处理过程的控制部分。 当确定盒未被先前打开时,控制部分通过使用蓝色激光器执行用于启动信息介质的第一开始处理过程。 当确定盒已经被预先打开时,控制部分确定信息介质是否是通过使用除了蓝色激光器之外的激光器执行开始处理过程的信息介质。

    • The optical disk drive of the present invention can read data from multiple types of optical disks and includes: a motor for spinning a given optical disk; at least one light source for radiating light beams with multiple different wavelengths; at least one lens for converging each light beam onto the disk; a spherical aberration correcting section that can change the spherical aberration states of the beam; and a control section for controlling the operations of the motor, light source, lens and spherical aberration correcting section. The control section includes a disk type recognizing section that irradiates the disk with a light beam using the light source and the lens, thereby recognizing the type of the disk. The recognizing section performs the recognition by reference to first and second signal waveforms that have been generated based on the light beams reflected from the optical disk when the spherical aberration correcting section sets the spherical aberration states of the light beam to first and second states, respectively.
    • 本发明的光盘驱动器可以从多种类型的光盘读取数据,包括:用于使给定光盘旋转的电机; 用于辐射具有多个不同波长的光束的至少一个光源; 至少一个用于将每个光束会聚到所述盘上的透镜; 球面像差校正部,其能够改变所述光束的球面像差状态; 以及用于控制电动机,光源,透镜和球面像差校正部分的操作的控制部分。 控制部包括使用光源和透镜照射光束的盘型识别部,从而识别盘的种类。 当球面像差校正部分将光束的球面像差状态分别设定为第一和第二状态时,识别部分参考基于从光盘反射的光束产生的第一和第二信号波形进行识别 。
