Abstract
To measure the strength of ferrites for video heads of small-size video tape recorders, deflection, crack, and scratch tests are performed. The breaking point of the ferrites is approximately 1/10 to 1/8 of that of Alfesil. As to the single crystal ferrites, the strength reduces about 20-25% when a tension is applied to the
