What Is Data Reduction?

- Jul 03, 2018-

Data reduction refers to a technique that seeks to reduce the amount of data needed to store music. Sony used ATRAC compression coding technology in its MD magneto-optical disc recorder, while Philips, the Netherlands, adopted a similar PASC (Precision Adaptive Sub-Band Encoding) technology in its DCC digital cassette tape drive. Both of these methods use data compression to try to remove data that is inaudible to the human ear.
