Abstract: A first home position icon and a plurality of second home position icons, which are first hierarchical level icons, are displayed on a menu item selection screen. When one of the second home position icons is selected, second hierarchical level submenus, as well as the first home position icon and the second home positions, are displayed on the menu item selection screen in a direction perpendicular to a direction in which the selected second home position icon is located with respect to the first home position icon. When one of the displayed submenus is selected, a third hierarchical level menu is displayed on a submenu screen.

Abstract: In an optical information recording method and apparatus for performing the pre-write testing of test data for an optical recording medium connected to a host computer, an instruction for pre-write testing of test data inclusive of two predetermined continuous signals is received independently from a write command from the host computer. The pre-write testing of the test data is performed by supplying different laser driving currents for plural ones of pre-write testing areas of the optical recording medium to an optical information recording head in accordance with the pre-write testing instruction. The respective pre-write testing data are reproduced to determine a difference in an average voltage level between the two continuous signals of each test data.
