    • 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.
    • 具有减震装置的盘驱动器的致动器包括设置在盘驱动器的盖上的电磁体,设置在致动器的负载梁上的与电磁体相对的磁性材料,以及驱动控制部分 通过检测负载光束朝向和远离由外部冲击引起的光盘的振动来驱动电磁体。 当负载梁被外部振动或震动驱动到磁盘驱动器上时,向电磁铁供电,将负载梁固定在外壳上,直到振动停止。 因此,即使当对盘驱动器施加外部振动或冲击时,也可以最小化或防止对盘或致动器造成的损坏。

    • 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.
    • 用于记录和再现高密度数据的混合头。 用于记录和再现数据的混合头部包括用于记录和再现形成在滑块背面的数据的元件。 用于记录和再现数据的元件包括:能量源,用于提供加热要进行数据记录的记录介质的预定区域所需的能量;磁场施加器,用于向由所述记录介质加热的记录介质的预定区域施加磁场; 从能源供应的能量,数据再现器,用于从记录介质再现数据,允许磁场供应商将从能量源提供的能量传送到记录介质的预定区域的通道,防止 从通道传输的热量到通道周围的其它元件,覆盖隔热元件的写入磁极和磁场发生器,以向写入极产生磁场。 通过这种设计,可以防止或最小化通道产生的热量,以将能量传输到安装在通道周围的其他元件。 此外,可以防止由于通道产生的热而使通道周围的其它元件的特性变化。
