Digital recording

View this topic in
In digital recording, the analog signal of video or sound is converted into a stream of discrete numbers, representing the changes in chroma and luminance values (video) or air pressure through time, thus making an abstract template for the original sound or moving image. Beginning in the 1980s, music that was recorded, mixed and mastered digitally was often labelled using the SPARS code to describe which processes were analog and which were digital.

Signal processing for digital recording on patterned media

Jack Keil Wolf Signals, Circuits and Systems, 2008. SCS 2008. 2nd International Conference on, 2008

The exponential growth of storage density in magnetic hard disk recording is threatened by the superparamagnetic limit which sets an upper bound to the number of bits per unit area that can be reliably stored. In this paper, a new media for recording called patterned media is described. Some of the signal processing challenges which occur in both writing and ...


An error-control coding scheme for multispeed play of digital VCR

Seung Ho Kim; Sang Wu Kim IEEE Transactions on Circuits and Systems for Video Technology, 1995

A two-dimensional array code, referred to as product code, has been extensively used to combat the errors in digital image recording systems such as digital VCR. An error-control coding scheme for multispeed play of digital video cassette recorder (DVCR) is proposed and analyzed. The proposed coding scheme is shown to yield a significant performance improvement over the conventional scheme with ...


Band-pass filtering in holographic data storage

K. Kawano; K. Haga; J. Minabe; S. Yasuda; M. Furuki; Y. Ogasawara; K. Hayashi; H. Yoshizawa 2005 IEEE LEOS Annual Meeting Conference Proceedings, 2005

We propose a new recording method in which essential Fourier spectrum components for recovering digital data are abstracted. This method can reduce the noise of reconstructed data and the wasted dynamic range of media


The application of sputtered thin film in advanced recording tape media

Hwan-Soo Lee; J. A. Bain; D. E. Laughlin IEEE Transactions on Magnetics, 2004

Recording characteristics of CoCrPt-sputtered tape media with a thickness of 25 nm were investigated using an anisotropic magnetoresistive head. The sputtered tape media showed a high output, and a flat frequency response with a D50 value of 5500 fcmm (140 kfci) and a corresponding signal-to-noise ratio of 22 dB. Such sputtered tape media produced a sharp and symmetrical isolated pulse ...
