Abstract: An ink jet printer apparatus is adapted to secure a print cartridge which includes an open container having a top opening; a porous ink-absorbent in the container; a print head in ink communication with the porous ink-absorbent; a top cover lid adapted to be placed on the container, over the top opening, to close the container; and an ink conduit needle mounted on the top cover lid to longitudinally extend in a horizontal orientation above the porous ink-absorbent when the cover lid is placed on the container, so that a print ink can descend freely by the force of gravity from the ink conduit needle onto the porous ink-absorbent and from the porous ink-absorbent down to the print head.

Abstract: 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.

Abstract: 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.
