Mbé vs Meknes

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.

Meknes (Arabic: مكناس‎, romanized: maknās; Berber languages: ⴰⵎⴽⵏⴰⵙ, romanized: amknas) is one of the four Imperial cities of Morocco, located in northern central Morocco and the sixth largest city by population in the kingdom. Founded in the 11th century by the Almoravids as a military settlement, Meknes became the capital of Morocco under the reign of Sultan Moulay Ismaïl (1672–1727), son of the founder of the Alaouite dynasty.

Moulay Ismaïl created a massive imperial palace complex and endowed the city with extensive fortifications and monumental gates. The city recorded a population of 632,079 in the 2014 Moroccan census. It is the seat of Meknès Prefecture and an important economic pole in the region of Fès-Meknès.
