20080288970 | Method for Determining Whether a Same Disc is Loaded in an Optical Drive - The invention relates to a method for determining whether a same disc is loaded in an optical drive. The method comprises a step of measuring a time interval between a disc insertion event resulting from a disc insertion command and a disc ejection event resulting from a disc ejection command. It further comprises a step of comparing said time interval with a predefined value. The disc is meant as still loaded in said optical drive if said time interval is smaller than said predefined value. | 11-20-2008 |
20130263163 | EMERGENCY EJECTION PROTECTING MODULE FOR AN OPTICAL DISC DRIVE - An emergency ejection protecting module is disclosed to protect the emergency ejection device in an optical disc drive. When the optical disc drive reads/writes a disc, moving a protection door at the case to reveal an ejection hole causes an abnormal operation of the emergency ejection. The contact end protruded from the protection door activates a sensor to transmit an ejection signal to the optical disc drive, and the optical disc drive starts the ejection operation to protect the disc. | 10-03-2013 |
20140208337 | MEDIUM PROCESSING DEVICE, CONFIGURATION INFORMATION SETTING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM HAVING STORED THEREIN CONFIGURATION INFORMATION SETTING PROGRAM - A medium processing device includes a processor, the processor emits light to a medium by a light source and calculates spherical aberration information relevant to spherical aberration related to the medium based on a detection result of reflected light, determines an installation direction of the medium processing device based on the spherical aberration information, and sets configuration information relevant to an operation for the medium based on a determination result. | 07-24-2014 |
20140359643 | OPTICAL DISC DRIVE AND DISC DETERMINATION METHOD THEREOF - An optical disc drive comprises a flash memory, an optical pick-up head, a spindle motor and a control unit. The control unit generates a determination result according to whether the optical disc drive has a disc loaded therein, and stores the determination result into the flash memory when the optical disc drive receives a power. The control unit reads the determination result from the flash memory after receiving the power again, and determines whether to control the optical pick-up head and the spindle motor to execute the disc detection procedure according to the determination result. If the determination result is negative, whether the optical disc drive has a disc loaded therein is determined according to a rotation speed of the spindle motor. If the rotation speed is larger than a threshold value, the control unit determines that no disc is loaded in the optical disc drive. | 12-04-2014 |

20090094625 | DATA REPRODUCTION APPARATUS LOADABLE WITH CARD-SHAPED STORAGE MEDIUM - A data reproduction apparatus for reproducing audio data includes an insertion slot, formed to open horizontally, for loading a card-shaped storage medium. An ejector ejects the card-shaped storage medium through the insertion slot when operated externally. A cover is positioned outside the insertion slot, rotatable between open and closed positions, having a receiving surface, for extending outwards from a lower edge of the insertion slot when in the open position, to support a lower surface of the card-shaped storage medium moving inwards or outwards through the insertion slot on the receiving surface, and for covering the insertion slot when in the closed position, to close the insertion slot. Also, the cover includes first and second side guide projections, positioned on the receiving surface, for contacting lateral edges of the card-shaped storage medium, to guide during insertion and ejection. | 04-09-2009 |

20080244629 | MEDIUM IDENTIFICATION DEVICE - According to the present invention, during identification of recording medium type, positioning of a recording medium at a measurement position for measuring the recording medium is facilitated, and the number of sensors for measuring the recording medium is reduced. In addition to identifying recording medium type, the top/reverse of the inserted recording medium can also be identified by way of a simple construction. A recording medium identification device, which identifies the type of a recording medium inserted through an insertion slot, comprises a plurality of sensors arranged in a band-like region having a predetermined width, in a depth direction, and a plurality of sensors arranged in a band-like region having a predetermined width, in a width direction. Data of two types of dimensions, combining dimensions of the recording medium in the depth direction and the width direction, is acquired by respectively arranging the a plurality of sensors in two partially overlapping band-like regions arrayed forming an L-shape. A plurality of types of recording media can be identified with increased identification precision by identifying the type of the recording medium based on such combined data of two types of dimensions. | 10-02-2008 |
20090083772 | DISK DEVICE - There is provided a disk apparatus having a clamp structure, which can fix a disk in a stable manner with a simple construction. More specifically, the disk apparatus includes a hub having a disk inserting portion having a cylindrical plane in the outer part of one end and a disk receiving portion having a flat part and being pivotably supported, a head having an inner hole through which the disk inserting portion is fitted, facing toward one face of a disk, levitating and scanning above the disk and reading a signal recorded on the disk or recording a signal on the disk, the disk being held by the disk receiving portion, and a clamp unit holding the disk with the disk receiving portion. In this case, the disk receiving portion has an inclined or declined plane. Thus, the amount and direction of deformation of the disk, which is caused by clamping, are defined, and obtaining a stable amount of head levitation independently of temperature changes can prevent the occurrence of a distortion of the disk. Therefore, a decrease in head output, for example, can be prevented, and the reliability can be improved. | 03-26-2009 |
20090144761 | Disc drive device - A disc drive device includes a disc conveyance mechanism, a slide cam and a trigger slider. The disc conveyance mechanism has a cam driven element protruded on a movement route of the slide cam and a conveyance roller energized in a direction coming into pressure-contact with a disc by an elastic member. The slide cam has a cam contour part moving the conveyance roller in a direction being spaced apart from the disc against an elastic force of the elastic member while pressing the cam driven element. The cam contour part has a flat surface part formed in parallel to a moving direction of the slide cam, in order to move only the trigger slider, while restraining the slide cam by contact pressure of the cam driven element to stop the slide cam temporary, when conveying the disc inside a cabinet toward an aperture side of the cabinet. | 06-04-2009 |
20090187931 | DISC APPARATUS - A disc apparatus includes a player and a holder. The player is configured for reading an optical disc, the player comprising a first latching portion. The holder is configured for holding extra optical discs, the holder comprising a second latching portion. The first latching portion and the second latching portion are capable of attaching the holder to the player cooperatively. | 07-23-2009 |

A spindle motor disposed on the traverse rotates an optical disk with a non-data area. The release device is set on the traverse adjacent to the spindle motor. A first hole is formed on the traverse and located in a position corresponding to the non-data area. A release bar protrudes from a bottom of the casing for inserting into the first hole. A buffer is installed between the release bar and the traverse for isolating vibration. | 03-25-2010 |
