Abstract: A graphical user interface for accessing data can display hierarchical information in an efficient organized layout that users may easily navigate. In one embodiment, subject headings are contained within cells that form a column. Information related to the subject headings is contained within cells which are formed in rows that are adjacent and orthogonal to the column. The information contained within the rows of cells is related to the closest subject heading in the column. One of the cells contained within the rows is a focus cell. The user may activate the focus cell to access a lower level within the hierarchy of information where the contents of the focus cell become a subject heading in the cell within the column. The user may browse the data by selecting a non-focus cell causing the contents within the rows of cells to appear to move from cell to cell.

Abstract: An improved file system and method for incrementally recording data on compact discs is disclosed. The improved file system and method employs compact discs physically formatted in accordance with the so-called Orange Book specification. Files to be stored are selected from time to time and are divided into packets. The packets are then recorded in a program area of the compact disc together with link, run-in and run-out blocks in a format compatible with the Orange Book rules for linking incrementally recorded packets. File linking information is also stored with each file. If desired, files may, but need not, be recorded in a form compatible with existing CD-ROM and drivers adhering to the ISO-9660 standard. As selected files are recorded, file and directory information are stored in a first storage area either in a host system or in a track of the compact disc in a double linked and highly efficient format.
