Magneto optical recording system with a laser mounted on a slider

A recording system for recording data on a magneto optical recording disk having a recording surface including a recording layer, comprising:

• slider means adjacent to the recording surface of said recording disk and separated from the recording surface by a small distance, the slider means adapted to transverse said disk by transversing towards the center point of the disk and away from the center;
• laser light source means mounted adjacent said recording disk on said slider means for projecting a laser light towards said recording layer;
• photo-sensor means mounted adjacent said recording disk for receiving the light emitted from the laser source and outputting a signal in response thereto, the recording disk disposed between the laser source means and the photo-sensor means cooperating with the laser source;
• and
• magnetic biasing means mounted on the slider means for producing a magnetic field bias causing data to be written on said magneto optical recording disk, said magnetic biasing means including a magnetic pole core integrally formed on the slider means, and a magnetic coil, the magnetic coil being wound about the laser light source means and the magnetic core pole.
