A method is described for storing data on a target track of a recordable medium in a storage device via a magnetic write head therein. The storage device has an operating parameter having an operational range with extreme at which the writing of data to said device is prohibited. A first threshold within said range is defined and proximate said first extreme and delimits a first operational subrange. The method including the steps of: monitoring said operating parameter; and determining whether the monitored parameter lies within said first subrange and if so, performing a first predetermined operation to compensate for deleterious effects on data storage caused thereby.

Method and system for writing data to a magnetic storage device in a relatively cold or hot environment

A magnetic head including a shielded MR element which incorporates a low reluctance path between the shields to reduce interference picked up by inductive reading of the shields. The low reluctance path is provided outside a conductive loop of material which includes the MR element and its associated leads. The low reluctance path may include a magnetic short between the two shields.

Magneto-resistive head including a selectively placed low-reluctance

A load/unload device to remove the slider from the proximity of the magnetic recording surface of a disk in a disk drive whenever the disk is to be stopped. The load/unload device is a ramp-like wedge which extends generally radially from the center of the magnetic disk and to the magnetic recording surface of the magnetic disk. When the slider is moved toward the center of the disk by an actuator mechanism, the end of the load arm supporting the slider, referred to as a tang, will engage the inclined plane of the wedge and lift the slider from the surface of the magnetic disk as the slider is translated closer to the center of the disk. Once the slider has been removed from close proximity of the disk, the tang may engage a trough-like surface on the structure supporting the wedge and will effectively detent the position of the slider through the forces exerted on the tang by the load beam of the actuator. Thus the disk will be protected from undesirable and damaging impacts of the slider against the magnetic recording surface of the disk thereby prolonging disk utility.
