   As the standard tape speed for a compact cassette is 1 + 7 ⁄ 8 inches per second (4.762 cm/s) and a C60 cassette records 30 minutes per side, a C60 cassette in theory holds 281 + 1 ⁄ 4 ft (85.73 m) of tape. In practice there is some variation, for example Maxell quote their C60s as being 90 m (300 ft) in length.

   The Apple I introduced an expansion-card based cassette system similar to KCS, recording a single cycle of 2000 Hz for a space and a single cycle of 1000 Hz for a mark. This resulted in an average speed of about 1500 bit/s. The associated device driver in PROM offered an interactive mode that allowed users to write memory locations to tape.

   [58] [8] Double-layer CrO 2 cassettes have the lowest absolute noise among all the audio formulations; these cassettes generate less noise at 4.76 cm/s than a ferric tape at 19.05 cm/s. [53] Their sensitivity is usually also very high, but MOL is low, on par with basic Type I tapes.

   These spools and their attendant parts are held inside a protective plastic shell which is 4 by 2.5 by 0.5 inches (10.2 cm × 6.35 cm × 1.27 cm) at its largest dimensions. The tape itself is commonly referred to as "eighth-inch" tape, supposedly 1 ⁄ 8 inch (0.125 in; 3.175 mm) wide, but actually slightly larger, at 0.15 inches (3.81 mm). [8]
