Magnetically, but instead of using a simple linear track like on audio tape, they use closely spaced diagonal tracks where each track edge of tape to opposite edge of tape records one frame of the video. Audio is recorded on a narrow linear track, erasing that part of the video tracks, where part of the video blanking would record. When played backed, the missing part of the video blanking pulse is simply synthesized by timing circuits. It is just black level anyway.
To create the diagonal tracks the video head is a special cylindrical helical scan unit with 2 to 4 tiny heads spun through a slot at high speed by a synchronized brushless DC motor. The helix groove around the cylinder that guides the tape is angled such that as one head leaves the edge of the tape the next head enters, so there is always a video head in contact with the tape.
Digital video tape uses a similar diagonal track system, but lacks the separate linear audio track as the audio and video are encoded together in the same digital signal.

Do video tapes run out of the tape inside?
Video tapes do not run out of the tape inside them because the tape simply stops and reverses back to start as the media content progresses. Each movie has a known length and is therefore recorded on a tape that can accommodate that length.
What is DivX?
DIVX is a codec. Codecs (coder / decoder) are used to reduce the amount of data needed to store or stream a video signal. They can be hardware based, i.e. a physical unit that does the conversion or they can be software based, as used in PCs for example. In all cases, they compress the signal for delivery or storage and then uncompress it to put on to a display. DIVX is the trade name of one such codec. A video signal that has been compressed using DIVX needs a DIVX codec to convert the signal back into a viewable format.Digital video express

How does analog video tape and video camera cards sore data magnetically?
Most recently, as in analog VHS VCRs, the video signal is impressed onto a radio frequency carrier and that is what is recorded on the tape. Since the tape speed is slow, the signal is fed by a rotary transformer to a drum that turns at 1800RPM. Video heads on the drum receive the signal from the secondary side of the rotary transformer and convey it to the tape with the same mechanics as with an audio tape. Because the frequency is so high for the video carrier, the speed of the moving head versus tape must also be high. This is accomplished by the drum spinning so fast. The tape follows a tilted or helical path along approximately half the circumference of the drum and therefore a helical track is recorded, which is actually appears as a series of physical diagonal tracks on the tape. At the same time, a synchronizing signal is recorded on one edge of the tape with a stationary control head. The synchronizing signal is a series of pulses that tells the servos in the machine whether to speed up or slow down the tape travel speed and head speed (phase). This is evident to the user if there is a tracking problem, as the noise where the head leaves the tape each time around is then visible. Video drums have two (or more) heads so that the tape need only encircle the drum part way. During playback, the head signals are switched so that the head in contact with the tape is connected to the playback circuits. Back to the stationary head - the analog audio tracks are recorded on the opposite edge of the tape from the control track. This is a very simple explanation.
