    VHS: 450 m, magnó: 150 m. Ha tudnám fejből a standard lejátszási sebességeket... Persze a Google megmondaná.

    És meg is mondta. Egész jó a memóriád, liksoft :).

    Egy kis olvasnivaló - most esik csak le, hogy már nincs spoiler tag, szóval csak óvatosan! :) A kérdés szempontjából az utolsó bekezdés érdekes.

    The VHS cassette is a 187 mm wide, 103 mm deep, 25 mm thick (73⁄8 × 41⁄16 × 1 inch) plastic shell held together with five Phillips head screws. The flip-up cover that protects the tape has a built-in latch with a push-in toggle on the right side.

    The recording media is a 12.7 mm (½ inch) wide, approximately 800 foot long Oxide-coated Mylar magnetic tape that is wound between two spools. The tape speed for "Standard Play" mode (see below) is 3.335 cm/s (1.313 ips) for NTSC, 2.339 cm/s (0.921 ips) for PAL—or just over 2.0 and 1.4 metres (6 ft 6.7 in and 4 ft 7.2 in) per minute respectively.

    VHS machines pull the tape out from the cassette shell and wrap it around the inclined head drum which rotates at 1798.2 rpm in NTSC machines and at 1500 rpm for PAL, one complete rotation of the head corresponding to one video frame.

    A VHS cassette holds a maximum of about 430 m (1,410 ft.) of tape at the lowest acceptable tape thickness, giving a maximum playing time of about four hours in a T-240/DF480 for NTSC and five hours in an E-300 for PAL at "standard play" (SP) quality. More frequently however, VHS tapes are thicker than the required minimum to avoid complications such as jams or tears in the tape.
