Title: Digital sound recording and reproducing device
Inventor: MIZUKI HIROKATSU
IPC: G11B20/12
Filed: 1989-02-20
Abstract: PURPOSE:To adjust a data with its data in front and rear frames even when the data is lost over two frames at the time of special reproducing by shuffling the data over three frames. CONSTITUTION:A data in one frame is divided into A, B and C groups, and the number of tracks in one frame is settled as 5, numbering 1, 2... in transmitting order of the data. A shuffle is performed in such a way that, for example, data of 1, 16, 31... are allotted to 1 while data of 2, 17, 32... are allotted to 2, and this is repeated until track 15 by a shuffling encoder 1. At the time of shuffling, when a track pattern to be regenerated is (A), the track pattern to be regenerated becomes (B) without regenerating hatched line parts. In the case of a pattern (a), a data to be continuously lost is 2 bytes, and even in the case of (e) and (f) losing a data by two frames, only a continuous data of 4 bytes is lost. Consequently, at the time of special reproducing, when a shuffling decoder 7 is set to make the pattern (A) only, a data is not lost continuously more than 4 bytes, and an output data after interpolating modification 9 is nearly an input signal.
