Optical disc drive having a tray with guide supports and main circuit board

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.

Optical disc drive having pickup integrated with disc insertion tray

An optical disc drive including a housing, a tray that is installed in the housing and that is configured to receive an optical disc, which has a spoke region on a surface thereof, an optical pickup unit which is attached to the tray, a main circuit board which is installed on the tray and is operatively connected to the optical pickup unit, and a spoke sensor which is arranged on the main circuit board and corresponds to the spoke region of the optical disk.

Optical disc drive having a tray with a main circuit board and spoke sensor

Provided are a ground unit and a disk drive including the ground unit. The ground unit is disposed on a guide frame which is installed on opposite sides of a main chassis for guiding a guide chassis that is connected to a tray. The ground unit electrically connects the main chassis and the guide frame to each other.

Ground unit and disk drive having the same

Provided is a disc drive including a tray which receives a disc thereon, slides into and out of a main chassis, and includes a pickup transporting unit which linearly moves a pickup base in a radial direction of the disc. The disc drive also includes a lock release unit which is driven by the pickup transporting unit to release locking of the tray from the main chassis, and includes a lock lever unit which includes a supporting hole for rotating the lock lever unit, and a hook unit to be combined with a locking protrusion arranged at the main chassis.

Disc drive with lock release unit

Provided is a disc drive including a main chassis, and a tray, which may receive a disc thereon, and is arranged to slide into and out of the main chassis. The tray includes a pickup transporting unit which linearly moves a pickup base in a radial direction of the disc and includes a step motor and a lead screw. The lead screw includes a plurality of sections with different diameters.

Disk drive with enhanced lead screw

A disk drive that includes (i) a main chassis, (ii) a tray that is configured to have a disk removably mounted thereon and that is installed to slide into/out of the main chassis, and that includes a pickup transporting unit configured to move a pickup base back and forth in a radial direction of the disk, and (iii) a lock releasing unit that is arranged on the tray, that is driven by the pickup transporting unit, and that releases a lock of the tray from the main chassis.

Disk drive

A disc drive including a tray, a housing configured to receive the tray, a pickup device installed on the tray, and a spindle motor including a rotator having built therein a permanent magnet, a stator including a magnetic coil, and a rotation axis supporting portion that is configured to support a rotation axis of the rotator and fixed to the tray.

Disc tray body insert-molded with a motor base and a disc drive using the same

A disk drive including a main chassis; a tray on which a disk is to be removably mounted, the tray being installed to slide into/out of the main chassis, and including a pickup transporting unit that is configured to move a pickup base back and forth in a straight line in a radial direction of the disk. The pickup base includes an optical pickup installed thereon, The disk drive also includes a lock releasing unit that is arranged on the tray, is driven by receiving a driving force of the pickup transporting unit, and releases lock of the tray from the main chassis. The disk drive drives a lock releasing unit by using driving force of a pickup transporting unit.
