摘要:
Provided are an optical pickup and an optical information storage system including the same. The optical pickup includes a photodetector that receives a main light beam and a plurality of sub-light beams reflected from an information storage medium and diffracted by a diffracting element. The photo detector detects a tracking error signal using zeroth-order light as the main light beam and using one of first-order light and third-order light as the sub-light beam based on a type of an optical information storage medium.
摘要:
Provided are an optical disc drive and method for driving the optical disc drive. The method includes transporting a disc to a chucking position where a spindle is positioned using a loading roller, blocking power transferred from a loading motor to the loading roller, and chucking the disc on the spindle using power from the loading motor. Accordingly, damages to the disc caused by chucking may be prevented.
摘要:
A skew adjusting apparatus is provided. The skew adjusting apparatus includes a plurality of skew support members provided on a base mold coupled to a base chassis to have an elastic force, and a plurality of skew screws configured to couple a motor plate that supports a spindle motor to the base mold.
摘要:
An optical backup apparatus is provided and includes an optical storage device, an interface module to connect with at least one type of external storage medium, and a control unit to back up data from the external storage medium to the optical storage device in response to an external remote control operation.
摘要:
Provided is an optical disc drive including a tray disposed in a case of the optical disc drive. The tray includes a guide fixed to the case, and a rail connected with the tray. The guide guides the rail as the tray is moved in and out of the optical disc drive. The rail further includes a supporter that is configured to stably support the rail with respect to the guide to prevent derailment of the rail from the guide.
摘要:
Provided is an object lens driving device that includes a wire holder coupled to a support portion and on which an end of a plurality of suspension wires are fixed. The wire holder includes a first area supported on the support portion and a second area extending from the first area and on which the end of each of the plurality of suspension wires is fixed. In this example, a thickness of the second area is thinner than a thickness of the first area.
摘要:
A disc drive including a tray, a housing configured to receive the tray, a pickup device installed on the tray, and a main circuit board installed on the tray and connected to the pickup device.
摘要:
Provided are an objective lens driving unit that maintains the electrical connection between suspension wires and winding bosses. The objective lens driving unit includes a plurality of winding bosses disposed at a side of the frame, each having a projection formed at its end and extending in a direction in which a suspension wire extends.
摘要:
Provided are an apparatus and method of generating a tracking error signal, and an optical information storage system including the apparatus. The apparatus includes a bias signal generator for generating a bias signal for canceling a direct current (DC) offset of a push-pull signal using a tracking control signal generated by the tracking controller. Accordingly, an offset generated in a tracking error signal may be canceled or otherwise reduced using the bias single instead of using an additional side beam.
摘要:
A hybrid storage device is provided. The hybrid storage device includes a first storage part that comprises an interface device based on a first standard, a second storage part that comprises an interface device based on a second standard, and a connector for interface devices that is shared by the first storage part and the second storage part and comprises a plurality of pins.
