Mbé vs Imola

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

Imola (Italian: [ˈiːmola]; Emilian: Iommla, Romagnol: Jômla or Jemula) is a city and comune in the Metropolitan City of Bologna, located on the river Santerno, in the Emilia-Romagna region of northern Italy. The city is traditionally considered the western entrance to the historical region Romagna. The city is most noted as the home of the Autodromo Enzo e Dino Ferrari which formerly hosted the Formula One San Marino Grand Prix (the race was named after the nearby independent republic of San Marino, as Monza already hosted the Italian Grand Prix), and the deaths of Formula One drivers Ayrton Senna and Roland Ratzenberger at the circuit during the 1994 San Marino Grand Prix.

The death of Senna (three-times world champion) was an event that shocked the sporting world and led to heightened Formula One safety standards.
