Also in the late 1970s, "direct-to-disc" records were produced, aimed at an audiophile niche market. These completely bypassed the use of magnetic tape in favor of a "purist" transcription directly to the master lacquer disc. Also during this period, half-speed mastered and "original master" records were released, using expensive state-of-the-art technology. A further late 1970s development was the Disco Eye-Cued system used mainly on Motown 12-inch singles released between 1978 and 1980. The introduction, drum-breaks, or choruses of a track were indicated by widely separated grooves, giving a visual cue to DJs mixing the records. The appearance of these records is similar to an LP, but they only contain one track each side.
When were 'half speed' and 'digitally remastered' recordings being released?
A: late 1970s

For example, the Italian and French words for various foods, some family relationships, and body parts are very similar to each other, yet most of those words are completely different in Spanish. Italian "avere" and "essere" as auxiliaries for forming compound tenses are used similarly to French "avoir" and "etre". Spanish only retains "haber" and has done away with "ser" in forming compound tenses. However, when it comes to phonological structures, Italian and Spanish have undergone less change than French, with the result that some native speakers of Italian and Spanish may attain a degree of mutual comprehension that permits extensive communication.[citation needed]
Along with foods and family relationships, what sorts of words are similar in French and Italian?
A: body parts
