Latest Patents:

Spruit's latest patented inventions have demonstrated his brilliance in developing efficient methods and devices for recording optical information carriers. One of his recent patents, "Method and Device for Recording an Optical Information Carrier," describes a technique involving the use of radiation pulses to write marks representing data onto the carrier at varying writing speeds. The inclusion of a period of reduced radiation power after the last pulse, inversely proportional to the writing speed, enhances the recording process.

Another notable patent, "Method and Device for Recording an Optical Information Carrier," focuses on a rewritable phase-change material recording layer that can be directly overwritten by a pulsing laser spot. The method involves irradiating the material at a writing power level, followed by a cool-down period with lower power before erasing the data using higher power. The duration of the cool-down period depends on factors such as the spot size and/or linear velocity, optimizing the recording process for improved outcomes.
