摘要： A magnetic disc storage system includes a magnetic storage disc and a transducing head. During periods of inactivity the transducing head is dithered whereby the head is moved to tracks on the disc according to a number of criteria. The criteria includes wear reduction, power reduction, avoidance of textured zones, head cycling, increased fly height and clearing of debris carried on the head.

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.
摘要翻译：一种测量读/写头的飞行高度以形成飞高高度分布的方法，用于测量读/写头相对于盘驱动器的盘的飞行高度。固定的源写入信号被施加到读/写头的电感元件，产生具有杂散磁通场部分的磁通场。读/写头的磁阻元件与磁通场耦合产生初始场强信号。当盘旋转时，读/写头在那里飞过，降低了杂散磁通场部分的密度，从而减小了场强信号的幅度。场强信号的减小的幅度被校准到预定的操作飞行高度分布，以将读/写头的飞行高度与形成飞行高度分布的场强场的减小的幅度相关联。

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.
摘要翻译：本发明涉及一种斜坡加载盘驱动器存储系统，其具有改进的加载性能，并且由于在斜坡加载操作期间由滑块和盘表面之间的接触引起的静摩擦和损坏，故障的可能性降低。滑块通常包括耐磨垫，其允许改进的加载性能并且减小滑块和盘表面之间的粘性。焊盘还允许斜坡加载盘驱动器存储系统以斜坡加载/卸载模式或触点启动/停止模式运行。此外，提供了一种操作斜坡加载盘驱动器的方法，其中滑块在盘达到完全运行速度之前从斜面加载在盘表面上方。

摘要： A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system and texturing is provided to a landing zone region on the disc surface.
