  • Patent number: 8984543
    Abstract: Provided is an optical pickup device that compensates for an aberration caused by a beam splitter. When a beam of light is reflected from a disc and proceeds towards a beam splitter, the beam splitter is designed to allow the reflected beam to pass therethrough. However, the beam splitter can cause an astigmatism in the reflected beam due to diffraction. According to various aspects herein, an optical pickup device may include a compensation device that generates an inverse astigmatism to compensate for the astigmatism generated by the beam splitter.

  • Patent number: 8923106
    Abstract: An optical disc drive (ODD) includes one or more sensors which detect a user placing a disc in the loading path. In response, a process is triggered for sensing the thickness of a protective layer of the disc even while the disc is moving toward a turntable. An initial determination of the type of the disc (e.g. CD, DVD or Blu-ray®) can be determined based on the thickness and reported to a host computing device. The host, in turn, determines an application to load based on the disc type. The loading of the application can begin sooner than if the ODD waited until the disc was seated on the turntable to detect the disc type. A final determination of the disc type can be made while the disc is seated as well. The host is informed if there is a disagreement between the initial determination and the final determination.
