Betamax is a consumer-level analog videocassette recording format developed by Sony. It works by recording analog audio and video signals onto magnetic tape through helical scanning. The recorded information can then be played back by inserting the Betamax cassette into a compatible player.
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
the work a machine does is the work output what it takes to do the work is the work input
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
Betamax was created in 1975.
Go to Think Geek website they have a Betamax to HD-DVD converter
When VCRs first made it to the home market, there were two different systems- VHS and BetaMax. They used different sized tape cassettes. VHS proved more popular, and BetaMax went away.
Depends on your question.

You would have to have a Betamax VCR. Try ebay.
To use betamax through magnetism, you would need a betamax tape and a suitable magnetic playback device such as a betamax VCR. Insert the tape into the VCR, ensuring it is wound properly. The magnetic heads in the VCR will read the magnetic signals recorded on the tape to play back the audio and video content.

Both Betamax and VHS were first developed by Sony Electric Corporation. Sony sold what it felt was the inferior VHS technology to the their competitors, believing that the superior Betamax would win out in the marketplace.
The VHS has a superior shelf to the Betamax. Take a look a this doozy: http://wiki.ggc.usg.edu/mediawiki/index.php/VCR_vs._Betamax#VCR_vs._Betamax:_the_.22Format_War.22
