Abstract

Several types of metallophthalocyanines have been synthesized to study their optical absorption and recording characteristics. VOPc and TiOPc films, prepared by vacuum sublimation, exhibited excellent thermal stability. The optical spectra of VOPc and TiOPc showed that the absorptive peaks were located at (lambda) equals 726nm and 712nm respectively. Some new recording characteristics of VOPc and TiOPc thin films were found from the measurements of reflectivity contrast (RC) versus different parameters as follows: RC versus film thickness at (lambda) equals 780nm; RC versus laser power at pulse width (tau) equals 500ns, and RC versus recording pulse width at laser power (rho) equals 13mW. THe mechanism of optical recording process in VOPc and TiOPc films was discussed. The dynamic testing result of TiOPc WORM disk showed that its carrier-to-noise ratio (CNR) reached 45 d when disk rotation speed was 1800 rpm, linear velocity was 14.1M/sec, and recording frequency was 4 MHz. Both of VOPc and TiOPC were found good enough for image storing.
