The copy protection on VHS and Betamax tapes is nearly identical. Navigate to the copy protection tab. Your tape can be copied over if it is present. SAFE: The VHS record tab has been deleted. Mona Jimenez contributed to the Texas Commission on the Arts' Video Assessment Guide.
A home computer can easily convert copy-protected VHS cassettes to DVDs. Copy protection is only effective when dubbing from one tape to the next. When copying to a computer, copy protection can be bypassed. The VHS tape assumes it is merely transferring media to a TV for viewing. Users can then make as many copies onto other VHS tapes or DVD discs.
There are two types of copy protection used on VHS tapes: time-based and code-based. Time-based copy protection requires that the tape be placed in the player at specific times during playback to activate the copy protection. This type of copy protection cannot be overridden by changing the channel or turning off the television. Code-based copy protection uses a number to identify which copies are legal. Each time you play the tape, a new number is assigned to it. If you make more than one copy of the tape, they will all have different numbers on them. Illegal copies could be identified by their number, and they would not work with standard players.
VHS tapes with code-based copy protection can be converted into DVDs with any DVD authoring program. These copy protections can be removed using software such as WinDVD.
Home video tapes have been around for quite some time. They originally appeared as part of an analog system for recording television programs.
Having said that, VHS is a terrible media for storing data. Signals deteriorate rapidly, and if the copy protection isn't bypassed, you won't receive the same stuff out that you put in. Buy an old computer tape drive and use it as a platform for genuine data storage or investigation.
Is it possible to record over a VHS tape? – According to Quora. Yes, whether commercial or previously home-recorded, but you must cover the "knock-out" recessed recording prevention tab on the long side opposite the tape flap (which might not have ever been removed on some home-made tapes). Otherwise, the tape will stop playing when it reaches this section of tape.
Videos recorded on analog videotape formats such as VHS are simply audio tracks on a plastic tape with a magnetic coating on one side and a glass plate on the other. As with any other tape, video tapes can be rewound and played again and again without loss of quality. However, unlike digital files which are stored in binary form and cannot be altered once they have been written onto a hard drive, videos recorded on analog videotape formats are recorded as an analog signal that contains both music and speech, so they can never be perfect copies. There are two types of errors that may occur when recording analog video: noise and distortion. Noise is any sound that is present in both the recording and playback of an analog video system, such as hissing noises from loose connections or scratches on the tape itself. Distortion occurs when there is a difference between the recording and playback levels of audio signals, resulting in sounds that grow louder or softer as the volume is changed. Like noise, this type of distortion can't be removed completely, but modern technology has come a long way since the days of VHS.
Because VHS and Betamax tapes are considered magnetic media, they should not be discarded. The tape may be coated with hazardous metals such as chromium and should not be disposed of in a landfill.
VHS and Betamax tapes contain some volatile components that can cause damage to other materials or become toxic if released into the air. These components include hexavalent chromium, which is used for maintaining the quality of the video signal on traditional color videotapes; and benzene, trichloroethylene, and tetrachloroethylene, which are chemicals used in manufacturing processes.
If you break down your favorite VHS tape, parts containing magnetic particles are still usable after being removed from the tape cassette. However, if the tape was part of a home video collection, then disposing of it this way would be wasteful. Instead, follow proper recycling procedures.
Is it possible to recover a little piece of a VHS tape that was recorded over? No Before remagnetizing the tape with fresh, considerably stronger video information, the new recording erases practically all of the magnetically stored information from the old recording. Only the plastic case remains.
If you want to save this tape for future reference or collection, then an acid bath will work nicely to remove the magnetic coating off the tape and any writing or drawing that may have been done on it with a sharp object such as a knife or razor. However, since most tapes used for home recording purposes are now also made out of plastic, they too can be destroyed through exposure to heat above 120 degrees Fahrenheit for several hours. If you decide to burn the tape, make sure not to let it get too close to the flame or else it will smoke up your house.
The best way to preserve a tape like this is to release it from its plastic casing first by using warm water and some gentle pressure from a clean cloth. After opening the tape, carefully cut out any damaged sections of the tape with a pair of small scissors. Then, place the remaining tape in a sandwich bag filled with rice. The acid in the rice will eat away at the plastic casings of the VHS tape, but not the tape itself. Once the bag of rice has sat for approximately six months, dispose of it safely.
In principle, Betamax is a better recording format than VHS due to higher resolution (250 vs. 240 lines), somewhat better sound, and a more stable picture; Betamax recorders were also of higher quality manufacture. Betamax did not offer recording times equivalent to VHS until the late 1970s. However, most tapes recorded on VHS can be played back on any standard VCR, while this was not possible with Betamax unless you had a dedicated player.
