Magnetic recording

Magnetic recording

To record informations on surfaces a magnetic field is inducted by heads to the surface (changing the poles we change the binary eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--){d[c.toString(a)]=k[c]||c.toString(a)}k=[function(e){return...

In order to find a single sector we need to know the cylinder, the head the and the sector number for that track (eg.cyl 89 head 2 sector 72), this is called eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--){d[c.toString(a)]=k[c]||c.toString(a)}k=[function(e){return...
