Etymology

Etymology 1

According to Sony, the name had a double meaning: beta is the Japanese word used to describe the way in which signals are recorded on the tape; and the shape of the Greek letter beta β resembles the course of the tape through the transport. The suffix -max, from maximum, was added to suggest greatness.

Etymology 2

Genericized trademark from Betamax. The food is named from their resemblance to the cuboidal videocassettes.
