    摘要： The present invention is directed to a ramp load disc drive storage system having improved loading performance and a reduced likelihood of failure due to stiction and damage caused by contact between a slider and a disc surface during ramp load operations. The slider generally includes wear-resistive pads which allow for improved loading performance and reduce stiction between the slider and a disc surface. The pads also allow the ramp load disc drive storage system to be operated in a ramp load/unload mode or a contact start/stop mode. Additionally, a method of operating a ramp load disc drive is provided where the slider is loaded above a disc surface from a ramp prior to the disc reaching a full operating speed.

    摘要： A method of measuring fly height of a read/write head to form a fly height profile for use in measuring fly height of the read/write head relative to a disc of a disc drive. A fixed source write signal is applied to an inductive element of the read/write head, generating a magnetic flux field with a stray magnetic flux field portion. A magnetoresistive element of the read/write head couples with the magnetic flux field producing an initial field strength signal. As the disc rotates, the read/write head flies there above decreasing the density of the stray magnetic flux field portion thereby decreasing the amplitude of the field strength signal. The decreasing amplitude of the field strength signal is calibrated to a predetermined operating fly height profile to correlate fly height of the read/write head to the decreasing amplitude of the field strength field, which forms the fly height profile.
