Abstract:
1. A tape drive head, comprising: a set of one or more servo readers designed for reading a servo pattern of a linear recording tape for positioning of the tape drive head, each of the servo readers of the set having: a sensor adapted for sensing a magnetic field component of a servo pattern; a first shield and a second shield, one on each side of the sensor, the shields configured to shield spurious components of magnetic fields occurring upon reading the linear recording tape, wherein: a gap between the first shield and the second shield is between 0.4 μm and 1 μm, and a minimal width of the sensor, the first shield and the second shield is between 0.5 μm and 4 μm, the width defined in a direction perpendicular to the gap, in a sensing plane of the sensor, the first shield and the second shield.
