A voice coil actuator return path and a slotted flex circuit member for a linear actuator of a disk drive, which together accurately and precisely position the center guide track, and align the mass and forces of the electrical circuit on the carriage are disclosed. The outer return path is precisely formed from laminations of low carbon steel. The outer return path supports and accurately positions a central guide track, on which a carriage assembly slides. Moreover, the outer return path is oriented in a rectangle that is coupled to a disk drive platform, and includes an aperture through which a portion of the carriage assembly passes. A flex circuit member, which electrically communicates with the read/write heads, includes a slot that enables the central guide track to pass though. The slot enables the flex circuit member to be connected to the carriage assembly near a center axis of the carriage. The flex circuit member has a center of mass and center of force approximately equally distributed on each side of a vertical plane passing through a centerline of the central guide track.

A method and apparatus for protecting against overwrite and misread errors caused by cartridge movement is disclosed. The apparatus comprises a read/write head and a read-write protection switch in electrical communication with the read-write head wherein the read-write protection switch generates an electrical signal upon movement of the media cartridge that disables the read/write head. The method of misread and overwrite protection comprises: detecting movement of the cartridge shell; disabling read/write heads; identifying whether the media drive was in the process of reading from or writing to the media cartridge; if the media drive was writing to the storage medium when the cartridge shell is moved, generating a write fault interrupt; and if the media drive is reading from the storage medium when the cartridge shell is moved, generating a read fault interrupt. A removable media cartridge having a push member and an abutment surface is also disclosed.
