The surface of a golf ball 2 is divided by four comparting great circles CG into six spherical quadrangles Ss and eight spherical triangles St. Micro-localized regions of a reflection format hologram extending throughout the medium are deleted by focusing a high-power laser beam at desired storage locations. Also, it engages an abutment of the housing by using a claw at the leading end of the protrusion. The method further comprises storing the preview placeholder template, and retrieving the preview placeholder template from storage and rendering a thin version of each of one or more list items. A second data transfer means receives the data provided by the memory bus and modifies, based on the received data, the data stored in the first buffer register during a second phase of the data write operation started by the reception of a second command. The real-time backward rewriting includes overlaying a subset of previously written data points with the new data points, and painting a remainder of previously written data points outside the subset in the scatter plot, where painting the remainder of previously written data points is performed without shifting pixels corresponding to the remainder.
