Abstract
In a process for producing a magnetic disk cartridge by welding two cassette shell halves for constituting a cassette shell of a magnetic disk cartridge to each other, a first fitting part is formed on an inner side of one of the two cassette shell halves. The first fitting part serves to adjust the position of the one cassette shell half with respect to the position of the other cassette shell half. A second fitting part is formed on an inner side of the other cassette shell half, which second fitting part is to be fitted to the first fitting part in order to adjust the position of the other cassette shell half with respect to the position of the one cassette shell half. Projections for ultrasonic welding are formed on a fitting surface of at least either one of the first and fitting parts. While the first and second fitting parts are being fitted to each other, energy of ultrasonic welding is concentrated upon the projections for ultrasonic welding, and the two cassette shell halves are thereby welded to each other.
