摘要： An actuator of a disc drive having a shock damping device includes an electro-magnet disposed on a cover of the disc drive, a magnetic material disposed on a load beam of the actuator, opposite to the electro-magnet, and a driving control portion controlling a driving of the electro-magnet by detecting an vibration of the load beam towards and away from an optical disc that is caused by an external shock. When the load beam is vibrated by the external vibration or shock to the disc drive, electricity is supplied to the electro-magnet, securing the load beam to the cover until the vibration ceases. Accordingly, even when there is external vibration or shock applied to the disc drive, possible damage to the disc or the actuator can be minimized or prevented.

摘要： A hybrid head to record and reproduce high density data. The hybrid head to record and reproduce data includes an element to record and reproduce data which is formed at the back side of a slider. The element to record and reproduce data includes an energy source to supply energy required to heat a predetermined region of a recording medium to be data-recorded, a magnetic field applier to apply a magnetic field to the predetermined region of the recording medium heated by the energy supplied from the energy source, a data reproducer to reproduce data from the recording medium, a channel to allow the magnetic field supplier to transmit the energy supplied from the energy source to the predetermined region of the recording medium, a heat shield element to prevent heat from being transmitted from the channel to other elements around the channel, a write pole covering the heat shield element, and a magnetic field generator to generate a magnetic field to the write pole. With this design, it is possible to prevent or minimize heat generated by a channel to transmit energy from being transmitted to other elements installed around the channel. In addition, it is possible to prevent the characteristics of the other elements around the channel from being changed due to the heat generated by the channel.

摘要： An apparatus to drive a blade on which an objective lens is mounted including a first electromagnetic unit to generate a first electromagnetic force and a second electromagnetic unit to generate a second electromagnetic force such that when the first and second magnitudes are the same, the blade is driven in a focus direction, and when the magnitudes are different, the blade is driven in a tilt direction. Accordingly, a tilt error can be actively controlled so that a laser beam is incident on a disk in a precise direction therefore improving the qualities of recording and reproducing data. In addition, tilt control is performed by using a focus adjustment mechanism so that an additional mechanism to control tilt is not required. As a result, the size and weight of the apparatus to drive the objective lens of the optical pickup are reduced.

摘要： An optical pickup actuator includes a base having a holder installed at one side thereof, a moving portion in which an objective lens is installed at the periphery thereof and a guide hole is formed, a bobbin coupled to the guide hole, a magnetic driving portion provided at the base and symmetrically arranged to make the moving portion perform focusing and tracking, and suspensions having one end supported at the holder and the other end fixed to the moving portion to be connected to the bobbin. Thus, since the magnetic driving portion is symmetrically arranged, a pitching mode and a rolling mode generated due to an asymmetrical structure are prevented. Also, the AC sensitivity and DC sensitivity can be improved.
