Control Magnetization Curve (CMC) and switching characteristics of amorphous tape wound cores with tape thickness ranging from 5µm to 17.5um have been examined. CMC is a constant current flux reset characteristic, which was measured up to 1MHz. A core with thinner tape exhibited a larger value of specific core gain in a wide range of control magnetizing force. Switching characteristics of the cores indicated that such a difference in CMCs reflects different mechanism of flux reversal. A core with thinner tape has stripe shaped domain pattern intersecting tape surfaces up to MHz region while a core with thicker tape has planer domain at that frequency.
