microgroove

These are generally not suitable for 78rpm records and early microgroove recordings.

In the early days of microgroove records (1940-1960), nickel plating was only brief, just an hour or less.

Another example of M/S stereo is the stereophonic microgroove record.

Daniels' recordings cover the period of transition from 78-rpm to the dawn of microgroove recording.

Meanwhile, on the other side of the Atlantic, Americans have been enjoying Microgroove releases since 1948!

One purpose of Microgroove rifling was to increase the speed of producing rifle barrels.

This was one of the earliest of the long-playing records made by Columbia, who had introduced the microgroove format in 1948.

Tubes with MicroGroove technology can be made with copper or aluminium.

This created considerable interest in the United States, and served to raise the customer's overall expectations of quality in microgroove records.

They evolved by the 1950's into the 12-inch, 33 1/3-r.p.m. microgroove LP.

However, MicroGroove offers higher heat transfer efficiencies than aluminium microchannel tubes.

Copper MicroGroove is a small-diameter coil technology.

The album was released on April 25, 2006, in Canada and the United States on the Microgroove label.

The ARC focuses on commercially released popular music on record, created since the advent of microgroove recording in the mid-1940s.
