Slider and the disk apparatus using the same

The present invention, by forming the groove structure surface into a predetermined shape, the area of ​​the relative speed of the slider / disk is small space or air bearing surface is said to be small, in difficult areas to ensure the air flow rate, air securing the amount of air flowing into the bearing surface, it can provide excellent slider atmospheric pressure variation characteristic. The present invention provides a negative pressure utilization type slider, apart from the negative pressure generating recess, a said inlet end side direction of the air flow in the pressure generating surfaces between the disc inner peripheral end side and the disk outer peripheral edge side of the air inflow surface to form a groove structure surface is lower than the air inflow surface height.
