VERSION 5.8. DELTA
==================

Wie der Changelog berichtet, wurden nun auch alle
deutschen Extraseiten der Homepage auf das Seitendesign
umgestellt. Ausserdem viele Korrektionen auf englischen
Seiten sowie Menue-Anpassungen und Designanpassungen.

Den Ordner /shared/img/fresh.design/dev gibt es jetzt
auch mal unter Versionskontrolle, weil u.a. einige neue
Seitenhintergruende zusammenkommen.

    3434    <p>The installations from the UNIVAC 9000 series (like our <a href="/en/devices/univac9400/univac_9300.shtm">UNIVAC 9300</a>) were equipped with plated wire storages. We could offer pictures of our storage units, but the assembly of this type of memory is quite opaque. Therefore we publish self-drawn diagrams to illustrate the plated wire characteristics.</p>

    36     <p>From the physical point of view the magnetical core memory is a thin-film storage medium. The information carrier is a 1 micrometer thick permalloy solenoid film (the "word strap") that is stacked on the "plated wire", that is a beryllium copper wire with 0.13mm in diameter.</p>

    42     <p>That plated wire constists of copper with a thin film which consists of an iron-nickel alloy. These plated wires are embedded into word straps which are perpendicular to two sides of the plated wire. In the easy direction of magnetization (see diagram above), the magnet layer is quite stable, whereas it is unstable in the hard direction of magnetization.

    4345    <br/>To read the information, the word current is raised. The current will establish a magnetic field which tries to align the magnetization vector at the area in the plated wire covered by the word strap.
    4446    Lengthwise, the magnetic film is very hard to magnetize, therefore the vector only librates (insteads of rotating) <!--and falls back to the former position after the word current was lowered.-->
