摘要： A recording density improvement method of a hard disc drive and a control device thereof are provided to increase TPI by keeping recording current value at the critical value when the recording current has reached the critical value. A recording density improvement method of a hard disc drive comprises a first step of applying recording current corresponding to the record signal to a magnetic head(110) of the hard disc drive, and a second step of limiting the current applied to the magnetic head to the predetermined critical value when the recording current has reached the critical value. The critical value is high frequency, the maximum record current applied to the magnetic head in recording. The second step is performed by a clamping circuit(127) arranged between the magnetic head and a pre-amp(126).

摘要： A device for erasing data of a magnetic recording medium is provided to perform a data erasing process conveniently by indicating a mark displaying the completion of data erase automatically. A data erasing device(1) for a magnetic recording medium has a marking system(20). The marking system, which forms an erase completion mark on a magnetic recording medium(2) whose data is eliminated, comprises a marking unit(21), a support(22), an elastic member, a cam(24), a driving unit(25), and a sensor(26). The marking unit forms the erase finish mark on the magnetic recording medium. The support is connected to the marking unit and moved vertically. The elastic member compresses the support to a side of the magnetic recording medium and provides elastic force to hit the magnetic recording medium by the marking unit. The cam moves the support vertically against the elastic force of the elastic member. The driving unit powers the cam. The sensor detects the data erase completion and sends a driving signal to the driving unit.
