Mbé vs Maca

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.

Lepidium meyenii, known as maca or Peruvian ginseng, is an edible herbaceous biennial plant of the family Brassicaceae that is native to South America in the high Andes mountains of Peru. It was found exclusively at the Meseta de Bombón plateau close to Lake Junin in the late 1980s. It is grown for its fleshy hypocotyl that is fused with a taproot, which is typically dried, but may also be freshly cooked as a root vegetable.

If it is dried, it may be further processed into a flour for baking or as a dietary supplement. It also has uses in traditional medicine. As a cash crop, it is primarily exported as a powder that may be raw, or processed further by the supplement industry: gelatinized or made into an extract. Its Spanish and Quechua names include maca-maca, maino, ayak chichira, and ayak willku.
