Abstract: A time and work tracker that automatically collects and analyzes information about time and work performed on a wireless device is described herein. According to the present invention, a time and work tracking function is initiated on a wireless device. Thereafter, a user begins to perform work on the wireless device. As the user works, the tracking function on the wireless device collects data relating to the activities performed by the user. The collected data is then analyzed to determine what types of work the user has actually performed.

Abstract: An optical disk has grooves and lands located on the disk. A predetermined distance between the grooves and lands is defined as a predetermined track pitch. The predetermined track pitch is defined in term of a laser wavelength used during an operation. The grooves have a depth “d” in relation to the lands. The depth is related to a parameter variable “a” and a refraction index “n” of a substrate.

Abstract: The invention relates to methods for making mold tools. More particularly, the mold tools are used for molding a resin substrate which has fine pits, i.e., concavities and protuberances. The invention also pertains to a method for manufacturing a resin substrate. Such resin substrates may be used as an optical disk, a magnetic disk, a hard disk, etc., for recording data. According to a preferred embodiment of the invention, a first metallic (Ni) mold tool (father) is made which is a duplicate of a master substrate, then a resin mold tool (mother) is made which is a duplicate of the first metallic mold tool and finally a second metallic (Ni) mold tool (son) is made which is a duplicate of the resin mold tool. Both the father and son may be referred to a “stamper”. The invention also relates to methods of manufacturing a mold tool for molding the base of an optical disk having at least one signal recording region and at least one non-signal recording region.

Abstract: A hybrid magnetic-optical head apparatus wherein one or more solid state lasers, magnetic field biasing elements, magnetic sensing elements, and an aerodynamically shaped slider comprise a single integrated, monolithic device fabricated from the same base semiconductor material into an optical head. The monolithic optical head can be quickly and easily attached to the read arm of an optical read/write device without requiring attachment of separate laser and magnetic elements, and without micropositioning or use of optical microscopy for positioning the lasers or magnetic elements. The hybrid magnetic-optical head apparatus includes a magnetic-optical function region having a semiconductor laser and at least one magnetic element. Preferably, the magnetic-optical function region of the substrate includes a magnetic field biasing element associated with the semiconductor laser, as well as a magnetic sensing element.

Abstract: An apparatus and method for moving a carriage assembly from an initial position to a target position relative to a storage medium rotating at a circumferential velocity. A processor determines a velocity trajectory relative to the radial distance of the initial position and the target position to the center of the medium, the circumferential distance between the initial position and the target position, and the initial circumferential velocity of the medium. The processor directs the drive to move the carriage assembly using the velocity trajectory so that the carriage assembly will arrive radially and circumferentially at the target position at substantially the same time. Additionally, the rotation of the storage medium may be changed from the initial circumferential velocity to a target circumferential velocity.
