Self Cleaning Cleaner Block for Cleaning Flexible Magnetic Media

The device as depicted in Fig. 1 shows a cleaner block 10 positioned relative to the magnetized surface of magnetic media 20 for cleaning debris from the media.

Cleaner 10 comprises a support 12 and a blade G. The material from which blade G is manufactured is nonmagnetic nickel based tungsten carbide. Since this material is nonmagnetic, the problem of magnetizing blade G which in turn erases prewritten information on magnetic media 20 is eliminated.

Blade G includes a vacuum slot C. Vacuum slot C is approximately 0.060 inch wide. Positioned on either side of slot C are projections B and K. By removing material from side L and side M of blade G so that angle A is formed with the horizontal surface of tape 20, only the flat portion (projections B and K of blade G makes contact with the surface of magnetic media 20.

In operation, pressure is applied to slot C from a pressure source, not shown. The applied pressure in combination with angle A pulls the tape in the direction shown by arrow 22, thus giving a high-loading force to the flat surfaces of blade
G. With the tape loaded against projections B and K, debris which is deposited on the magnetic media is removed via vacuum slot C. In addition, loose particles which may be on magnetic media 20 are also removed by vacuum slots F.

The fact that vacuum slot C is approximately 0.060 inch coupled with the fact that the amount of pressure which is applied t...
