Abstract
A tape drive read/write head assembly that utilizes a magnetic shield to help protect the head from any magnetic flux that strays from the tape drive's motor. The head assembly includes a voice coil motor, a transducer head (typically a read/write head), and a carriage carrying the head. The carriage is movably coupled to the motor. The magnetic shield is positioned at least partially between the head and the motor. In one preferred version of the invention, the shield is a metal plate sandwiched between the head and the carriage. It is desirable to make the shield from a high nickel content metal or similar type material that has a large magnetic flux carrying capacity with a small magnetizing force.
