There is provided a disk recording apparatus capable of minimizing a servo error and recording in the last zone at the maximum one of the recording speeds specified in the apparatus or disk recording medium even if the disk recording medium is in poor condition. The memory is dynamically partitionable in private memory areas for storing data therein and has associated therewith a secrecy tool for securely allocating to the users respective private areas and permitting the users to access the respective private areas via a secure session channel to perform readwrite commands in the respective private areas. The first skew comprises a combination of raster output scanner skew and media path skew. The power output connector cables can also be stored within storage cavities formed in the charger housing when not in use and extended therefrom for connection with electronic devices in need of recharging. Similarly, a three terminal hybrid MOSFETbipolar high voltage switching device can be formed by replacing the first high voltage bipolar transistor of the previous switching device by a high voltage MOSFET. The method includes the steps of obtaining data representing the plurality of features; and forming at least one of the plurality of features by etching a substrate to form a mesa and depositing a chrome layer over the entire upper surface of the mesa, where said mesa has a predetermined height.
