Mbé vs Rancho Cucamonga

Informations

In computer science, group coded recording or group code recording (GCR) refers to several distinct but related encoding methods for representing data on magnetic media. The first, used in 6250 bpi magnetic tape since 1973, is an error-correcting code combined with a run-length limited (RLL) encoding scheme, belonging into the group of modulation codes.

The others are different mainframe hard disk as well as floppy disk encoding methods used in some microcomputers until the late 1980s. GCR is a modified form of a NRZI code, but necessarily with a higher transition density.

Informations

Rancho Cucamonga was a 13,045-acre (52.79 km2) Mexican land grant in present-day San Bernardino County, California, given in 1839 to the dedicated soldier, smuggler and politician Tiburcio Tapia by Mexican governor Juan Bautista Alvarado.

The grant formed parts of present-day Rancho Cucamonga and Upland. It extended easterly from San Antonio Creek to what is now Hermosa Avenue, and from today's Eighth Street to the mountains.
