Patent number: 6034926Abstract: A media stackloader processes removable data storage media cartridges containing optical disks, magnetic diskettes, or tape media. A moveable rail on the stackloader locks cartridges in the stackloader. The rail is pivotable on the stackloader to permit access to a cartridge so that the rail can be pivoted to a position where the cartridges are locked in the stackloader or to a position where cartridges can be removed and replaced in the stackloader. A locking solenoid engages the moveable rail to permit or prevent pivoting of the rail.Type: GrantFiled: February 2, 1999Date of Patent: March 7, 2000Assignee: International Business Machines CorporationInventors: Chi-Hung Dang, Kamal Emile Dimitri, John Edward Kulakowski, Rodney Jerome Means

Patent number: 5933395Abstract: A media stackloader processes removable data storage media such as optical disks, magnetic diskettes, or tape media. The stackloader removably couples to a storage drive, such as by plugging into a slot of the host computer. The stackloader has a plug portion integral with a housing portion, the plug portion plugging into the host computer and the housing portion housing a magazine containing the removable media. The stackloader includes a device for moving the magazine vertically within the housing to align selected cartridges with an opening in one of the drives of the personal computer. After the cartridge is aligned, a device is employed for moving the cartridge horizontally into the drive for processing and, after processing, for withdrawing the cartridge from the drive back into the magazine. A locking mechanism selectively locks and unlocks the cartridges to prevent improper removal of cartridges from the magazine.Type: GrantFiled: September 25, 1997Date of Patent: August 3, 1999Assignee: International Business Machines CorporationInventors: Chi-Hung Dang, Kamal Emile Dimitri, John Edward Kulakowski, Rodney Jerome Means

Patent number: 5787446Abstract: A file management system facilitates both physical and logical file groupings with convenient access to surplus media for sub-volume expansion. Each item of media includes a local file directory, which provides a list of files stored on the medium, cross-referenced to the files' addresses on the medium. The media items are organized as one or more primary sub-volumes, an auxiliary sub-volume, and a media reservoir. Each primary sub-volume preferably comprises a single sub-directory, and includes one or more media items used to store files of a specific class. Initially each primary sub-volume includes a single piece of media. The library also includes at least one auxiliary sub-volume, which may include multiple sub-directories, to store leftover files that do not fall under classes corresponding to the primary sub-volumes. Files may be stored on the auxiliary sub-volume on a random, "space available" basis.Type: GrantFiled: June 19, 1997Date of Patent: July 28, 1998Assignee: International Business Machines CorporationInventors: Chi-Hung Dang, Chi-Thanh Dang

Patent number: 5778374Abstract: A file management system for accessing mass storage systems, employing a compressed common file directory ("CCFD") that occupies a minimum amount of storage space. The CCFD is implemented in a storage system including a library of media, one or more storage drives that may be permanently or selectively coupled to the media, and a controller connected. Each piece of media includes a local file directory, which contains a listing of the files stored on that piece of media cross-referenced to those files' addresses on the media item. The controller contains or has convenient access to the CCFD. When access to a file is desired, the CCFD is used to quickly identify the piece of media containing that file. More particularly, the CCFD includes a first data structure including a list of encoded filenames cross-referenced to a list oil compressed media IDs. Each encoded filename comprises a filename of a file stored in one or more of the media, encoded with a selected encoding scheme.Type: GrantFiled: August 3, 1995Date of Patent: July 7, 1998Assignee: International Business Machines CorporationInventors: Chi-Hung Dang, Chi-Thanh Dang

Patent number: 5715216Abstract: Data storage apparatus having an array of cartridge-storing receptacles with a media device at one extremity of the array, provides cartridge input-output either at all of the receptacles or at a predetermined number of such receptacles. The media device may face the travel of an accessing mechanism such that a holder in accessing mechanism loads a cartridge onto the media device while the holder is situated at the media device. Interlock means prevent the removal of cartridges while the accessing means holder is active in an IO range of the receptacles. Moving the accessing means out of the IO range of receptacles, such as to the media device, enables manual insertion and removal of cartridges. A plurality of the cartridges are kept in respective slots of the cassettes. These cassettes are removably inserted into respective ones of the receptacles.Type: GrantFiled: April 26, 1996Date of Patent: February 3, 1998Assignee: International Business Machines CorporationInventors: Chi-Hung Dang, Chi-Thanh Dang

Patent number: 5680377Abstract: An automated data storage library of unique design includes a plurality of storage cell magazines containing storage cells for holding storage media cartridges therein. A picker mechanism having multiple direction capability is positioned for accessing and transporting the storage media cartridges between at least three adjacent storage cell magazines. The picker mechanism includes a pair of gripper pickers configured for releasably gripping and supporting the storage media cartridges during transport between the storage cells. The picker mechanism is rotatable so that one of the grippers can be utilized to access two of the adjacent storage cell magazines while the second gripper accesses the third storage cell magazine. For increased efficiency, the picker mechanism can be positioned between opposing columns of storage cell magazines together with a single storage cell column at one end.Type: GrantFiled: May 31, 1995Date of Patent: October 21, 1997Assignee: International Business Machines CorporationInventors: Chi Hung Dang, Chi Thanh Dang

Patent number: 5663938Abstract: A checkerboard data storage library is provided which includes a plurality of receptacle modules and a plurality of picker modules. The receptacle modules and the picker modules are arranged alternately side by side in a closed loop planar array. Each receptacle module has a plurality of open-ended receptacles arranged one above the other in a column which extends perpendicular to the planar array. Each open-ended receptacle is capable of receiving and storing a recording medium. Each picker module has a picker which reciprocates vertically in a respective column opposite open ends of the receptacles in receptacle modules for transporting recording media therebetween. The above arrangement facilitates simpler expansion of the library and assures its operability even though one or two picker modules should fail.Type: GrantFiled: November 15, 1995Date of Patent: September 2, 1997Assignee: International Business Machines CorporationInventors: Chi-Hung Dang, Chi-Thanh Dang

Patent number: 5652742Abstract: The present invention provides a retainer system of an automated storage and retrieval system, or library, which prevents information storage elements, or cartridges, from escaping from their respective storage cells when the entire library is transported from one location to another. The retainer system comprises a retractable cable, a null, or dummy, cartridge, and an array of storage cells. One end of the retractable cable is attached to the null cartridge and the other end of the cable is affixed to one end of the array of storage cells. Initially, the null cartridge is positioned in a storage cell located adjacent to the end of the storage array where the cable is affixed. When all the information storage elements are placed inside their respective storage cells within the array, the null cartridge is moved from its original position to a storage cell at the opposite end of the storage array.Type: GrantFiled: September 29, 1995Date of Patent: July 29, 1997Assignee: International Business Machines CorporationInventors: Francisco Antonio Baca, Chi-Hung Dang, Jerry Walter Hammar
