Abstract

PURPOSE:To stabilize movement between tracks and prevent a magnetic disc and a magnetic head from damages by attaching inclined planes faced in the direction of air flowing between a slider and a magnetic film on both sides of a floating magnetic head which are opposed to the moving direction of the floating magnetic head. CONSTITUTION:Inclined planes S1, S2 with an inclined angle theta of about 30 deg. to a horizontal plane are attached to both sides of a slider of a floating magnetic head at a right angle to a direction A to move a selected track. The thickness of the slider is about 2mm., the depth is about 10mm. and the dynamic lift is obtained from the inclined angle theta and the inclined planes S1, S2. The floating magnetic head can keep a floating interval larger than 0.38-0.6mum which is the floating interval between the floating magnetic head and a magnetic film required for recording and reproduction by the dynamic lift due to the wind velocity of about 2m/s generated by the movement. Thus, the flying form of the floating magnetic head can be stabilized at the time of movement between the recording tracks and accidented damages due to contact between the floating magnetic head and the floating film can be prevented.
