The present invention provides a method of synthesizing libraries of molecules which include an encoding oligonucleotide tag. The copolymer may be prepared from a reaction mixture that contains 1,4-cyclohexane dicarboxylic acid and poly diamine. The binder contains as a primary component a water-insoluble polyester resin having a high hydroxyl value in the range of 25 to 65. Layers including the antiferromagnetic layer, a free magnetic layer, and layers therebetween, have planes preferentially oriented. The indication device is preferably mounted on a front of the base plate adjacent the blind bore.
