    • An optical disk drive according to the present invention has the ability to read data from multiple types of optical disks, each of which includes at least one information storage layer. The drive includes: a driving mechanism 120, which is loaded with a selected one of the optical disks of the multiple types and which rotates the optical disk 102; an optical pickup 30 for irradiating the optical disk 102, which has been loaded into the driving mechanism 120, with a converged light beam, thereby generating an electrical signal based on light that has been reflected from the optical disk 102; and a control section (ODC 50) for controlling operations of the driving mechanism 120 and the optical pickup 30. The control section 50 includes a right/wrong side determining section for determining, by reference to the electrical signal generated by the optical pickup 30, whether or not the optical disk 102 has been loaded into the driving mechanism 120 with the other surface opposed to the optical pickup 30.
    • 根据本发明的光盘驱动器具有从多种类型的光盘读取数据的能力,每种光盘包括至少一个信息存储层。 该驱动器包括:驱动机构120,其装载有选择的多种类型的光盘并使光盘102旋转; 用于以会聚的光束照射已经装入驱动机构120的光盘102的光学拾取器30,从而基于从光盘102反射的光产生电信号; 以及用于控制驱动机构120和光学拾取器30的操作的控制部分(ODC 50)。控制部分50包括右/错侧确定部分,用于通过参考由光学拾取器30产生的电信号, 光盘102是否已经被装载到具有与光学拾取器30相对的另一表面的驱动机构120中。

    • An optical disk apparatus according to the present invention is an optical disk apparatus for performing at least one of: recording data to a plurality of types of optical disks including a recordable optical disk and a read-only optical disk which are produced according to the BD specifications; and reproducing data from the optical disks. This apparatus includes: a means (506, 507) for irradiating a management area 502 of an optical disk 501 with a light beam while not performing tracking control, and generating a track position signal (push-pull TE or phase difference TE) from light which is reflected by the management area 502; and a disk determination means for determining, based on the track position signal obtained from the management area 502, whether the optical disk 501 mounted in the optical disk apparatus is a recordable optical disk or a read-only optical disk.
    • 根据本发明的光盘装置是一种用于执行以下至少一项的光盘装置:将数据记录到根据BD制造的包括可记录光盘和只读光盘的多种类型的光盘 规格; 并从光盘再现数据。 该装置包括:用于在不执行跟踪控制的同时用光束照射光盘501的管理区域502并从光线产生轨道位置信号(推挽TE或相位差TE)的装置(506,507) 这由管理区域502反映; 以及盘确定装置,用于基于从管理区域502获得的轨道位置信号确定安装在光盘装置中的光盘501是可记录光盘还是只读光盘。

    • 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。
