ABSTRACT:
A disk cartridge comprises top and bottom opposed spaced-apart plates defining a compartment in which an information recording disk is rotatable. A front peripheral wall joins the top and bottom plates with an aperture in the front peripheral wall communicating with the compartment. The disk cartridge is provided with a brake mechanism that latches the disk axially and radially in an operative plane until the cartridge is inserted fully into a drive mechanism. The brake mechanism also functions to protect the disk against damage, abrasion, cracking and the like, by eliminating annoying rattling when the cartridge is jostled during transporting or in handling. The disk brake mechanism comprises a unitary spring-biased pivotally mounted brake member on one side of the disk center for engaging the periphery of the disk and clamping the disk between the brake member and a pair of angularly spaced nooks located on the opposite side of the disk center.
