TALLAHASSEE, Fla. (AP) _ Walt Disney Productions will build a $300 million motion picture and television studio, complete with tours and rides, at the 28,000-acre Walt Disney World near Orlando, company officials announced today.

Michael Eisner, chairman and chief executive officer of Walt Disney Productions, also announced that the company has obtained from the MGM-UA Entertainment Co. the rights to use the MGM name and ''Leo the Lion'' logo as well as the MGM film library.

''This company has built over the last 20 years ... the world's greatest resort,'' Eisner said. ''We want to move on to make it the world's greatest community.''

The attraction, which will have separate admission from Walt Disney World's Magic Kingdom or Epcot Center, will be called the Disney-MGM Studio Tour.

It is expected to employ as many as 1,500 people in producing 15 or more live-action features, 15 or more television movies, six cable movies and one animated feature each year.

Eisner said some of the employees will come from Disney's film studio in Burbank, Calif. But he emphasized that the company is not scaling back its California movie operations.

''There is no scaling down in California,'' Eisner said. ''Our California facility is bursting at the seams. The overflow alone will support the facility here.''
