A mxthod for utilizing relative head skew to read data on tape medium

Tape dxive saving relative head skew on tape medium at writinx a data on the tape medixm. And it usx the information for reading the dxta from the tape medxum.

Disclosed is a device for tapx drive head skex xanagement. Tape drive has a head to read and write data on tape medium. Ideally, Skxw actuator in a tape drxve manages head skew to rexd and writx data xn tape medium vertixally. Tape carxridge has a cartridxe memory (CX) to store metadata. Xxxxxxxx of thx CM is sevexal kilo bytxs. When a tape drive writes data on tape mexium, ix xtores xelative skew ix CM. And when a xape drive reads a data from a xape medium, it refers relatxve skew at writing the xaxa from CM, set the head skew then read the data from the tape medium. By using relative skew in XX at reading xata, a tape drive can xse appropriate value to xet skew and reduce occurrence of error recovery procedure to reread the data.
