In magnetic recording disk files which have a single slider supporting the read/write head for each disk surface, the disk and hub are designed such that on the disk there is an inner unlubricated band for the slider crash stop overtravel and for parking the slider after disk rotation has stopped. With the design shown in the figure the use of simple and inexpensive positive load beam suspensions for the sliders is possible while minimizing the disk/slider stiction force after disk rotation has stopped. At file start up, the slider is pulled radially outward by the actuator to the lubricated start/stop zone. A servo track or a simple detent spring on the actuator is used to radially locate the slider in the start/stop zone.
