    摘要: The present invention relates to an optical record carrier (55) recording apparatus (5) such as a small form factor optical drive and to a portable device (1), such as a mobile phone or a palmtop computer, comprising such an optical record carrier (55) recording apparatus (5). To enable different accessing modes having different data rates depending on the power mode of the recording apparatus an appropriate switching means (53) is provided in the recording apparatus for switching accessing means (54) for accessing an optical record carrier (55) for reading data from or recording data to said optical record carrier (55) between said accessing modes. A first accessing mode has a low data rate and is used in a low power mode while a second accessing mode has a high data rate and is used or allowed to be used in a high power mode.

    摘要: A disk drive unit for a disk, e.g. for use in a mobile device, comprises a spindle (1) positioned within the disk drive unit and adapted to support the disk rotatably in an operating position. An electric motor (2) is operatively coupled to the spindle (1) to rotate it. An auxiliary electric motor (3) is connectable to the spindle to accelerate the spindle during start-up. This auxiliary motor can be selected to work efficiently at zero speed. The electric motor may be a low-power motor, resulting in a reduced power consumption.

    摘要: An apparatus processes the data contained in this carrier (1) by moving (rotating) it. The motor, which rotates the data carrier needs angular information on the rotary part of the motor for commutation. For measuring accurately this angle, marks are placed on the data carrier. A detector senses these marks so that the measurement of the angle is easily performed. Application: The invention is well suited for small sized optical discs.
