    Abstract: A method is presented to rotate a read/write head rotatable along a first axis and comprising a first assembly having a first servo element and a second servo element. The method moves a sequential information storage medium adjacent to the read/write head along a second axis, wherein the second axis is substantially orthogonal to the first axis, and determines the rotation angle for the read/write head with respect to the sequential information storage medium using the first servo element and the second servo element. The method then positions the read/write head with respect to the second axis based upon the rotation angle.

    Abstract: An apparatus, system, and method are disclosed for aberration compensation. In one embodiment, a first compensation lens used in conjunction with a second compensation lens to produce a conical beam used to read from, or write to, an optical medium. An Nth order compensation equation is used to optimize aberration errors associated with accessing the optical medium. The present invention may include a displaceable focus lens positioned relative to an optical medium. The focus lens may be displaced when the conical beam's focal length is adjusted. A displacement equation is presented to determine the preferred placement of the focus lens. By compensating for aberration, read/write errors may be reduced while accessing optical media thus increasing system robustness and facilitating the use of additional layers on optical media.

    Abstract: A method to set a rotation rate for an optical holographic data storage medium by determining if the optical storage layer comprises an alternating series of lands and grooves. If the optical storage layer does not comprise an alternating series of lands and grooves, the method rotates the optical holographic data storage medium at a rotation rate based upon a data acquisition rate for pit-recorded information. If the optical storage layer comprises an alternating series of lands and grooves and the distance between alternating grooves increases as a function of the distance from said center point, then the method rotates the optical holographic data storage medium at a constant angular velocity. If the distance between alternating grooves does not increase as a function of the distance from said center point, then the method rotates the optical holographic data storage medium at a constant linear velocity.
