He joined Sony Japan in 1964 and started the first digital audio project within Sony. He was the driving force behind the PCM adaptor, and was a prominent member of the Sony/Philips taskforce responsible for the design of the Compact Disc.[1] He created, among others, the CIRC error correction system.[2] He, with Kees Immink, refutes the myth that the Compact Disc's playing time was determined by Beethoven's Ninth Symphony.[3]
He was the lead engineer of the DASH multi-track digital audio tape recorder.[4] In the 1990s, he headed Sony's Digital Creatures Laboratory, where he was responsible for the Aibo,[5] Sony's robotic dog. In 2003, Doi created the Qrio, a running humanoid robot.
