 and Blu-Ray Disc. He has been a prolific and influential engineer, who holds more than 1100 US and international patents. The impact of his work on consumer electronics is so large that it is virtually impossible to enjoy digital audio or video that does not reflect his work. His contributions to coding systems jump started the digital video and audio revolution, by enabling reliable data storage at information densities previously thought unattainable.

Immink received several tributes that summarize the impact of his contributions to the digital audio and video revolution. Among the accolades received are the Edison Medal  for a career of creative contributions to the technologies of digital video, audio, and data recording, and an individual Technology Emmy award by the National Academy of Television Arts and Sciences
