Magnetic data recording/reproducing device having a linear motor which includes a pair of coils integrally assembled with a carriage assembly on both sides thereof

摘要

In a magnetic data recording/reproducing device comprising a linear motor mounted on a main plate for driving a carriage assembly having a magnetic head, the linear motor comprises a pair of coils integrally arranged with the carriage assembly on both sides thereof and a pair of magnetic circuit devices for generating magnetic fields in a direction intersecting that of electric currents flowing through the pair of coils. The linear motor further comprises a cover plate fixed to the main plate such that the pair of magnetic circuit devices are held on the main plate. The cover plate is integrally provided with a pair of urging members for urging the pair of magnetic circuit devices from upward.
