Abstract
A flexible disk file employs a pivotable head arm which supports a grooved magnetic head. The magnetic head is formed with an asymmetric groove so that skew of the head relative to the rotating flexible disk surface is compensated.
Claims4
A magnetic head assembly useful for transducing coaction with a flexible magnetic disk comprising:
- a support arm;
- a magnetic head mounted to said arm, said head having a contoured face with a centrally located transducing gap;
- first and second grooves formed on said contoured face and symmetrically disposed about said transducing gap with the axes of said grooves being substantially perpendicular to the axis of said transducing gap;
- third and fourth grooves formed on said contoured face and disposed parallel to said first and second grooves and spaced symmetrically about said first and second grooves and said transducing gap, said first and third grooves being located inboard of said gap, said second and fourth grooves being located outboard of said gap;
- an offset groove formed on said contoured face outboard of said fourth groove towards the outer portion of said head relative to the periphery of said disk, all of said grooves being substantially parallel on said contoured face.
