Atomic isa micro programming language designed forthe full digitalђ EVERSDM, MD, SW and SM family drives. The scope of this language is to givethe userthe freedom tocreate his own simpleapplication withouthaving to switch tomore complexand more expensive drives. Atomics philosophyis to havefew but powerful instructions. The programmingof Atomic is done by meansof user friendly Personal Computerwiththe Atomicenvironment and anSDM, MD, SW or SM drives withґAtomic Ready logo and Atomicfirmware (c0499). > Atomic -March, 27th 2007Pag. 2 of 20. size="-1">
