head efficiency this effect can be compensated by decreasing the overall length of the yoke structure thereby decreasing its contribution to the magnetic reluctance and therefore restoring the head efficiency to a higher value this loss in head efficiency could in principle also be improved by increasing the width of the yoke structure which increases the effective cross section of the path through which the magnetic flux can flow however this approach also increases the cross section area of the leakage paths between the two yokes comprising the write head structure which thereby increases the overall head inductance since this is not a desirable consequence the preferred embodiment would be to make the yokes as narrow as possible consistent with the application requirements and recover the loss of efficiency by making the yoke structure shorter as described herein yet another key feature of the head 74 are the first and second pole tip layers 92 and 94 which are formed in a 34 pedestal 34 shape as with the pole tip layers 14 and 16 fig3 layers 92 and 94 minimize the sensitivity of the head performance to final lapped throat height fig1 shows a variation of the magnetic head 74 implemented with laminated first and second yoke layers 84 and 86 respectively in the first yoke layer 84 an insulating layer 104 is sandwiched between two sub layers 84a and 84b likewise in the second yoke layer 86 another insulating layer 106 is interposed between two sub layers 86a and 86b laminating the yoke layers 84 and 86 prevents the formation of eddy currents during high frequency operations an exemplary eddy current path 108 is shown in fig1 eddy currents can flow.
