Description
(54) МАГНИТНАЯ ГОЛОВКА(54) MAGNETIC HEAD
ВAT
, мируюш,ий неред рабочим зазором поле стирани (поле на чертеже не показано). Прот женность пол стирани определ етс общей толш,иной прокладки. При однородной прокладке прот женность пол стирани в направлении, перпендикул рном плоскости магнитного носител (на чертеже не показан ), приблизительно равна половине прот женности пол в направлении движени носител и значительно превышает толшину последнего или толшину его рабочего сло . Это приводит к излишнему потреблению энергии, к потере мош.ности. Введение магнитом гкого сло в прокладку уменьшает эти потери, а выполнение комбинированной йрокладки с соотношением толщин немагнитнбго , следующего за ним магнитом гкого 15 и вновь немагнитного слоев 1:2:1 позвол ет не только резко уменьшить потребл емую мощность по С1 авнению с головками, в которых уже используетс комбинированна прокладка, но иуменьшить величину тока стирани . Этому также помогает то, что толщина всей прокладки составл ет не менее 1,,5 единиц от длины волны сигнала и то, что глубина прокладки, т. е. ее рассто ние от поверхности головки до кра прокладки , превышает глубину сформированного25 с ее помощью рабочего зазора на величинуот О до 20%. Peaceful, erase field is non-working (the field in the drawing is not shown). The length of the wipe floor is determined by the overall thickness of the pad. With a uniform gasket, the length of the erasure field in the direction perpendicular to the plane of the magnetic carrier (not shown) is approximately equal to half the length of the field in the direction of movement of the carrier and considerably exceeds the thickness of the latter or the thickness of its working layer. This leads to excessive energy consumption, loss of mosh.nost. The introduction of a soft layer into the gasket reduces these losses, and the implementation of a combined layer with a ratio of non-magnetic thicknesses that follow a soft 15 and again 1: 2: 1 non-magnetic layers makes it possible not only to drastically reduce power consumption with C1 which a combined pad is already used, but to reduce the amount of current erasure. This is also helped by the fact that the thickness of the entire gasket is at least 1, 5 units from the signal wavelength and that the depth of the gasket, i.e., its distance from the surface of the head to the edge of the gasket, exceeds the depth of the formed25 with its help a gap on magnitude of About to 20%.
