2. INTRODUCTION
• Developed by Sony, Released in Japan May
10, 1975.
• Format for Videocassette Recording (VCR).
• Machine Designed to deliver Home Video-
Taping equipment.
• After introduction of Philips VCR in 1972.
• BETA means “the way signals are recorded” ,
MAX means “Maximum”
• It Is also known as ‘Beta’ Greek letter beta (β)
3. FEATURES
• VCR is an electro-mechanical device
which is used for recording and
playing back. It uses magnetic tape
recording format.
• Betamax provide better Picture
Quality.
• Initially, It provide one hour of video
recording.
4. FEATURES (CONT.)
• Later In 1977, Sony introduced Betamax SL-8200 which provide
two hour recording time.
• Betamax Cassette is smaller in size than VHS, it contains
12.7mm wide video tape.
Betamax SL-8200
5. BETAMAX UPGRADATION
• Betamax HIFI: In 1984, High Fidelity
audio- sound with little distortion,
Frequency to 400kHz.
• Super Betamax: in 1988, frequency
till 800kHz.
6. FAILURE OF BETAMAX
• Rival JVC developed VHS system (Video Home System) just a
year later its introduction. Which developed Videotape Format
War.
• Weak marketing strategy.
• Short recording time (VHS could record for six hours and
Betamax only for two hours max).
• Refused to License their format.
7. FAILURE (CONT.)
• Mass manufactured object (VHS was about 29 Ibs and
Betamax was about 36 Ibs)
• Ownership goes down & VHS took 95% of market share.
• Overweening pride, Sony claimed that it is technically
superior model
• Sony's decision to ignore VHS.
8. DISCONTINUATION
• Betamax Recorder discontinued in 2002
• On Nov 10, 2015. Sony Announced that Betamax tape will
cease manufacturing by march 2016.
9. SUGGESTIONS
• Improve marketing strategy (what customer wants:
reduced Cost Increased recording time)
• Should move with the changing environment
(Technological Advancement)

In June 1983, Sony introduced high fidelity audio to videotape as Beta Hi-Fi. For NTSC, Beta HiFi worked by placing a pair of FM carriers between the chroma (C) and luminance (Y) carriers, a process known as frequency multiplexing. Each head had a specific pair of carriers; in total, four individual channels were employed. Head A recorded its hi-fi carriers at 1.38(L) and 1.68(R) MHz, and the B head employed 1.53 and 1.83 MHz. The result was audio with an 80 dB dynamic range, with less than 0.005% wow and flutter.[16]
Prior to the introduction of Beta Hi-Fi, Sony shifted the Y carrier up by 400 kHz to make room for the four FM carriers that would be needed for Beta Hi-Fi. All Beta machines incorporated this change,
In early 1985, Sony would introduce a new feature, High Band or SuperBeta, by again shifting the Y carrier—this time by 800 kHz. This improved the bandwidth available to the Y sideband and increased the horizontal resolution from 240 to 290 lines on a regular-grade Betamax cassette. Since over-the-antenna and cable signals were only 300–330 lines resolution, SuperBeta could make a nearly identical copy of live television. However, the chroma resolution still remained relatively poor, limited to just under 0.4 MHz or approximately 30 lines resolution,
