    摘要： A liquid jet recording head such as an ink jet recording head has liquid passages having liquid outlets through which a recording liquid is discharged in the form of jet of droplet, and electro-thermal transducers for generating heat which produce energy for discharging the liquid in response to inputted electric signals. The electro-thermal transducer has a heat-generating resistance layer which is made of an amorphous material containing halogen atoms and hydrogen atoms in a matrix of carbon atoms. Disclosed also is a recording system incorporating this recording head. The amorphous material can further contain silicon atoms and/or germanium atoms.
