Apparatus and Method to Transfer Data to and from a Sequential Information Storage Medium

Abstract

A sequential information storage medium, comprising a plurality of servo patterns encoded lengthwise thereon, wherein each servo pattern encodes at least one LPOS bit and comprises a width less than 187 microns.

1 . A sequential information storage medium, comprising:
 a first end, a second end, a first side, an opposing second side, and a transverse axis orthogonal to said first side and said second side;   a plurality of servo patterns encoded lengthwise between said first end and said second end and adjacent said first side;   wherein each of said plurality of servo patterns encodes at least one LPOS bit and comprises a width less than 187 microns.   
     
     
         2 . The sequential information storage medium of  claim 1 , wherein each of said plurality of servo patterns comprises a width less than or equal to 103 microns. 
     
     
         3 . The sequential information storage medium of  claim 1 , further comprising 16 data bands encoded between said first plurality of servo patterns and said second plurality of servo patterns. 
     
     
         4 . The sequential information storage medium of  claim 1 , wherein each servo pattern comprises a plurality of bursts, and wherein each plurality of bursts comprises a plurality of pulses, and wherein each stripe is written to said sequential information storage medium at an offset angle with respect to said transverse axis, wherein said offset angle is greater than 6 degrees. 
     
     
         5 . The sequential information storage medium of  claim 4 , wherein said offset angle is greater than or equal to 12 degrees.
