摘要： Apparatus and method for generating an analog waveform, such as a deflection signal used to deflect a write beam during the writing of data to a rotatable medium having a variable track pitch (TP). In accordance with various embodiments, a first digital to analog converter (DAC) is configured to output a deflection signal having an analog voltage level corresponding to a magnitude of a first multi-bit digital input value applied to the first DAC. A second DAC is configured to supply a rail voltage to the first DAC having an analog voltage level corresponding to a magnitude of a second multi-bit digital input value applied to the second DAC. The deflection signal is used to deflect a write beam supplied by a write beam generator.

摘要： Method and apparatus for formatting a data storage medium, such as a magnetic or optical disc. In accordance with various embodiments, a data storage medium is rotated while a write beam is used to write data to the rotating medium. The data are written in the form of a plurality of concentric data tracks. A deflection angle of the write beam is continuously adjusted in an axial direction along each track. In some embodiments, the axial deflection of the write beam imparts a desired angular offset between a beginning point of a first track and a beginning point of an immediately adjacent second track. This allows a first translation geometry, such as a linear translation path of a linear actuator, to emulate a different second translation geometry, such as a rotary translation path of a rotary actuator.

摘要： An optical disc apparatus includes a withdrawal means for moving an objective lens (32) to a position distant from an optical disc (1) during an inactive duration of intermittent recording or reproducing operation. A means for regulating or fixing the objective lens (32) at the position distant from the optical disc (1) is further provided. Thus, even in a noncontrolled state during the inactive duration, it is possible to prevent collision of the objective lens (32) with the optical disc (1). As a result, both power saving and safety of the apparatus can be attained.
