Abstract:
A servo write head that provides fast servo pattern writing and improved tape manufacturing speed is provided. The write head may be fabricated using thin-film fabrication techniques. A coil is formed on a bottom pole of the write head. The coil has a plurality of turns that enable the write head to generate a magnetic field sufficient for writing data with reduced current. The inductance of the coil is reduced due to its small dimensions. Reduced inductance of the coil may enable increased switching frequency of the write head, allowing data to be written at a higher frequency. The write head includes a planar top pole coupled to the bottom pole. The top pole has more than one write gap is formed therein.
