MAGNETIC HEAD AND MAGNETIC RECORDING AND REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic head having long service life and high reliability by using a high hardness and strength glass composition without raising melting point. SOLUTION: The magnetic head is produced by using a glass composition containing a matrix phase including at least one of rare earth elements and crystalline particles which are formed from the same kind of element as the rare earth element and uniformly dispersed in the matrix phase.
