Recording Properties

In this section, we will examine some features of these two phenomena—room-temperature reversible photodarkening and photocrystallization—in amorphous semiconductors films of Sbj Sei j . For the starting material, pure amorphous Se was chosen. One of the elemental amorphous materials, Se may be extremely suitable for discussing essential features and relationship (if such exists) between the two phenomena chosen for discussion. In addition, the effect of small amounts of antimony (a few percent) on photodarkening and photocrystallization of a-Se is especially interesting— not only from the point of view of compositional disordering, but also because of desirable recording properties and peculiarities of electronic transport for amorphous Sb Sci films [25]. 

Magnetic Recording Properties. Typical values of physical properties of barium ferrite pigments used in magnetic recording are given in Table 38. 

The micromagnetic structure is directly related to the microstructure and chemical inhomogenities in the layer. The materials used and the deposition technology as well as the parameters play an important role. Thin-film growth, nudeation processes in relation to the deposition parameters, are very important for understanding the thin film microstructure. The relationships between sfd and recording properties are not necessarily valid for media with perpendicular anisotropy as the demagnetizing field can be more important than sfd. 

Hydrogenated amorphous semiconductors may represent a new class of recording materials. The recording mechanism is based on rapid hydrogen evolution or effusion within the recording layer. The recording properties of...

The above review of existing literature shows that httle is known about the fundamental reasons which determine properties of plasticized blends. With a few exceptions, papers record properties rather than analyze principles of their formation.

The systematization of the results of measurement is a normal scientific activity which leads to methods for the interpolation and extrapolation of data. For example, the Periodic Table may be used to seek relations between a thermodynamic property for compounds in a Group of elements. In the estimation of the properties of aliphatic compounds it is common practice to consider members of a homologous series, and therefore to study the change in a property produced by an increment of one CHa group. For this purpose it is often convenient to use the appropriate hydrocarbon homologous series as a source of reference. However, a word of caution is necessary here because some of the recorded properties of hydrocarbons have themselves been obtained by incremental methods,...
