DC-International is an audio cassette system introduced by Grundig in 1965. DC is an abbreviation of Doppel-Cassette (Double Cassette), since it is a two-reel cartridge. "International" was intended to indicate that from the beginning several companies were represented on an international basis with matching cassette tape recorders, pre-recorded music tapes and blank cassettes on the market. DC-International could not compete with the similar Compact Cassette (now better known as the standard audio cassette format)

The DC-International was presented at the radio exhibition in Stuttgart in 1965. Grundig was at that time the largest tape recorder manufacturers in the world and would therefore also be represented in the newly created audio cassettes market.

As with the Compact Cassette format, the DC International cassette consists of a reel-to-reel magentic tape mechanism enclosed in a user-friendly cartridge. The dimensions of a DC International cassette are 120 mm × 77 mm × 12 mm, and the weight is 65 grams. The housing is made of polystyrene, and includes a window (with scale) for viewing the tape inside. The cartridge has openings for the tape heads, capstan and pinch roller. A record lock against unintentional deletion is present in the form of two recesses in the cartridge. For protection, a protective case is supplied to hold the cassette when not in use.

The tape is loaded so that the magnetic layer faces outwards. On the tape there are two opposing tracks- the sound is recorded and played back in mono analogue. The tape is 3.81 mm wide, and the track width is 1.75 mm. The space between the tracks is 0.26 mm wide. The tape speed is 5.08 cm/s (2 inches/sec).

For a DC-90 cassette with 90 minutes running time (45 minutes per side), the tape length is 137 m with triple play tape (PES 18, thickness 0.018 mm). For a DC-120 cassette (2 x 60 minutes running time) the tape length is 185 m with quad band game (PES 12, thickness 0.012 mm). The strip material is made of polyester.

From the outset, 25 pre-recorded music cassettes of the brands Telefunken, Decca and RCA Victor were available. The repertoire of these ranged from Western to the Rolling Stones. Typical playing time was around 30 minutes per side, for about 60 minutes total playing time ( ≈ long-playing record ). The sale price of a recorded tape was 24 DM.

For one's own recordings, blank cassettes were available from the Grundig, Telefunken, BASF and Agfa brands. These empty cartridges were available as DC 90 (90 minutes running time) and DC-120 (120-minutes). A DC 90 empty cartridge cost 12 DM, a DC 120 blank cassette 15 DM.

DC-International compatible cassettes were still available a few years after the cessation of production equipment on the market.

===================

There are portable cassette tape recorders and appliances for installation in motor vehicles, all fully transistorized. As portable devices, there is the Grundig C100 cassette tape recorder as the first of Grundig and a similar model of Telefunken, the Magnetophon 401 Both devices are battery operated , with an additional charge power supply was available. This power supply is inserted into the battery compartment and disappears so completely in the device. The selling price of both units was 298 DM [16 ] [ 17] [18 ]

The Grundig C 100 was later replaced by the two slightly revised models Grundig C 100 L and the parallel model Grundig C 110. The Grundig C 110 can only be used in network operation. [19 ]

Built-in devices for motor vehicles are available as Grundig AC 50 for connection to an existing car radio and as Grundig AC 60 with integrated 5 watt amplifier and volume control and tone control for operating without a car radio. A radio receiver is not installed in this device. From Blaupunkt car models are available with tape-recorder I and car - II tape recorder These devices are identical to the Grundig models and were manufactured at Grundig. All car chassis units are pure playback devices, recording is not possible with it. [20 ] [ 21] setting Compare Compact Cassette DC International cassette

After two years, the system DC International was set in favor of the Compact Cassette. Telefunken was the Hannover Messe 1967, the setting known Grundig little later to the 25th Radio exhibition Berlin 1967. The interface presented Grundig C 200 is a cassette tape recorder for Compact Cassettes. [22 ] [ 23] List of pre-recorded cassettes
