Title: Innovations of Yuuki Fujiwara
Introduction
Yuuki Fujiwara is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of recording and reproducing apparatuses. With a total of 2 patents, his work showcases innovative approaches to data encoding and signal processing.
Latest Patents
Fujiwara's latest patents include a recording apparatus and a reproducing apparatus. The recording apparatus utilizes a first run length encoder to implement run length modulation of a first information signal. This process generates a second information signal of a run-length-limited code while applying DSV control and adding a sync signal. The converter then transforms this signal into an NRZI signal, which includes information code words. A parity generator produces original parity signals in response to these code words, combining them to form a first parity-added signal. A second run length encoder further processes this signal to create a second parity-added signal, which is recorded on a medium.
The reproducing apparatus reads a signal of a run-length-limited code from the recording medium. It converts this read-out signal into a reproduced digital signal. A decoder subjects the digital signal to first decoding, generating information bit streams that differ in timing. Run length decoders then process these streams to obtain run-length-decoded bit streams, which undergo error correction and detection. The stream with the fewest errors is selected and outputted as the most likely information bit stream.
