A thermite torch formulation that includes a metal fuel in the form of a magnalium alloy and an oxidizer in the form of MoO3. A first repeatable runout sinusoid is generated representing an RRO of the first disk surface, and a second RRO sinusoid is generated representing an RRO of the second disk surface. Results of this analysis are used to assign a respective block function to blocks of the document content. The method incorporates swap partition encryption using a cryptokey created each time during the boot of the remote computer. A display processing unit processes menu screen display and content reproduction.
