Abstract:
1. A disc drive comprising: a tray; a housing configured to receive the tray; a pickup that is operatively coupled to the tray; a connector installed on the housing configured to output signals obtained from the pickup; a cable, comprising a first end which is connected to the connector, a part installed adjacent to a side of a body of the housing, wire layers which transmit signals to a host, and wire layers which receive signals from the host; and penetration holes formed in a side of the body of the housing so as to reduce a capacitive coupling between the cable and the body of the housing, wherein the penetration holes are directly aligned with the wire layers which transmit signals to the host, and none of the penetration holes are aligned with the wire layers which receive signals from the host; and the penetration holes are arranged diagonally and periodically throughout an entire region of the housing, the region consisting of areas where the cable is in contact with the housing.
