An information writeread head writes or reads information on or from recording tracks by the heat-assisted system. It is possible to supply an electric power to the electrical conductor tracks, the electrical conductor tracks preferably being used to heat the first dielectric member, and the electrical conductor tracks being made of a material having a pronounced, positive temperature coefficient. The composition has a low viscosity, allowing for easy injection through standard hypodermic needles. The alignment control film is made from a polyamic acid obtained by reacting a diamine with an acid anhydride of 1,2,3,4-cycle butane-tetracarboxylic acid dianhydrides. The present invention also comprises a transformer that applies transformation rules to the phone dataset to produce a transformed phone dataset. The invention also relates to pharmaceutical compositions of these compounds and methods of using these compounds as antibacterial compounds.
