Recent developments in ultrahigh density magnetic storage technology rely on novel recording media with high magnetocrystalline anisotropy energy MAE together with high performance giant magnetoresistive GMR heads.

In the s the magnetic recording density of hard disk drives HDD increased every year and reached nearly the maximum value. Magnetic storage media and devices store data in the form of tiny magnetised dots.

These dots are created, read and erased using magnetic fields created by very tiny electromagnets. In the case of magnetic tape the dots are arranged along the length of a long plastic strip which has been coated with a magnetisable layer audio and video tapes use a similar technology.

A magnetic disk drive that shape coefficient is 3. When magnetic disk media are rotated in a higher speed, an electric power consumption and a heat generation are increased because of a load increase in rotating the magnetic disk media. An avoidance of such problems and setting an additional special cooling mechanism to magnetic disk drive systems, for example, disk array systems, is presented. A housing 11 of magnetic disk drive in a shape coefficient 3. Further, fins 11 a for heat radiation may be arranged around the housing 11, which results in avoidance or decrease raising a temperature in the housing

Он. Он должен быть. Дворик под названием Апельсиновый сад прославился благодаря двум десяткам апельсиновых деревьев, которые приобрели в городе известность как место рождения английского мармелада. В XVI11 веке некий английский купец приобрел у севильской церкви три десятка бушелей апельсинов и, привезя их в Лондон, обнаружил, что фрукты горькие и несъедобные.

Кровать застонала под его весом.  - Простите. Беккер вытащил из вазы, стоявшей на столике в центре комнаты, розу и небрежно поднес ее к носу, потом резко повернулся к немцу, выпустив розу из рук. - Что вы можете рассказать про убийство. Немец побелел.

Но Сьюзан тут же сообразила, что могла быть еще одна причина отключения Следопыта. Внутренние ошибки программы не являлись единственными причинами сбоя, потому что иногда в действие вступали внешние силы - скачки напряжения, попавшие на платы частички пыли, повреждение проводов. Поскольку за техникой Третьего узла следили самым тщательным образом, она даже не рассматривала такую возможность. Сьюзан встала и быстро подошла к громадному книжному шкафу с техническими руководствами, взяла с полки справочник с прошитым проволочной спиралью корешком и принялась его листать.
