	Gramophone record - Wikipedia, the free encyclopedia
		Disc records were invented by Emile Berliner in 1888, and were used exclusively in toys until 1894, when Berliner began marketing disk records under the Berliner Gramophone label.
		Unbreakable records, usually of celluloid (an early form of plastic) on a pasteboard base, were made from 1904 onwards, but they suffered from an exceptionally high level of surface noise.
		While a 78 rpm record is brittle and relatively easily broken, both the microgroove LP 33⅓ rpm record and the 45 rpm single records are made from vinyl plastic which is flexible and unbreakable in normal use.

	Analogue disc record
		An analogue disc record is a flat disc with inscribed spiral grooves, in which the playback process begins with the direct mechanical motion of a stylus riding within the groove as the disc rotates.
		Recording on disc as opposed to phonograph cylinder had been contemplated and experimented with by such inventors as Charles Cros, Thomas Edison, and Chichester Bell, but the first to actually develop usable disc record technology was Emil Berliner, a German working in Washington, DC, in 1884.
		All speeds of records were made in various sizes, mainly 7, 10 and 12 inches (18,20.5 and 30.5 cm aprox.) diameter; the 7-inch being most common for the 45rpm, the 10-inch for the 78 (and the first few years of 33⅓ production), and the 12-inch for the 33 from the mid 1950s on.

		The signal to be measured is fed to one of the input connectors, which is usually a co-axial connector such as a BNC or N type.
		The earliest and simplest type of oscilloscope consisted of a cathode ray tube, a vertical amplifier, a timebase, a horizontal amplifier and a power supply.
		These are now called 'analogue' scopes to distinguish them from the 'digital' scopes that became common in the 1990s and 2000s.

		Of the three live recordings included on the CD version (Musea FGBG 4128.AR) the most interesting is the ten-minute jam "Live in an Elevator" which shows the band can still maintain an immaculate melodic sense while jamming their heads off.
		Recorded at the Silver Elephant in Tokyo (a performance house for many Japanese prog acts, including Azoth and Un Known), this album contains fantasic live renditions of four songs from Four Corners Sky, two from Lost and Found and one new song.
		Although the English is a bit difficult to follow on the Black Rills Records web site regarding this release, I take it that the original master tapes of this session were lost, which I assume means it had to be remastered from one of the 200 original LP pressings.
