    • A magnetic disk unit includes slider suspension assemblies, each of the assemblies having a slider with at least one magnetic head element and a suspension with one end portion and one surface, the slider being mounted on the one surface of the suspension at the one end portion, magnetic disks, each of the disks having at least one surface which opposes to the slider of the assembly, head IC chips electrically connected to the magnetic head elements, and a control circuit electrically connected with the head IC chips. The control circuit controls operations of each of the magnetic head elements so that the write current is applied to the magnetic head element for a first predetermined period of time and then the application of the write current to the magnetic head element is stopped for a second predetermined period of time which is equal to or longer than the first predetermined period.
    • 磁盘单元包括滑块悬架组件,每个组件具有带有至少一个磁头元件的滑块和具有一个端部和一个表面的悬架,滑块在一端部安装在悬架的一个表面上 ,磁盘,每个盘具有与组件的滑块相对的至少一个表面,与磁头元件电连接的头部IC芯片,以及与头部IC芯片电连接的控制电路。 控制电路控制每个磁头元件的操作,使得写入电流在第一预定时间段内施加到磁头元件,然后停止对磁头元件的写入电流的施加第二预定的 时间段等于或长于第一预定时段。
