    • The invention relates to a data storage device (101) which comprises a data interface (103) for reading data from a spinning data storage disc (105). The data storage device (101) comprises a motor (111) for spinning the data storage disc (105) at a desired speed. The data storage device (101) further comprises a speed change processor (115) for determining a preferred motor speed change time; and a motor controller (113) for controlling the motor (111) to perform the speed change in response to the preferred motor speed change time. Specifically, the preferred motor speed change time resulting in the lowest energy consumption for disc spin-up and jump operations are determined, and the motor (111) is controlled to change the speed substantially within the preferred motor speed change time. The invention is particularly suitable for Small Form Factor Optical (SFFO) disc systems and allows for reduced energy consumption and thus increased battery life.
    • 本发明涉及一种数据存储设备(101),其包括用于从旋转数据存储盘(105)读取数据的数据接口(103)。 数据存储装置(101)包括用于以期望速度旋转数据存储盘(105)的马达(111)。 数据存储装置(101)还包括用于确定优选的电动机速度改变时间的变速处理器(115) 以及电动机控制器(113),用于响应于优选的电动机速度改变时间来控制电动机(111)执行速度变化。 具体地,确定导致用于盘升起和跳转操作的最低能量消耗的优选的电动机速度变化时间,并且控制电动机(111)以在优选的电动机速度变化时间内基本上改变速度。 本发明特别适用于小型光学(SFFO)光盘系统,并且能够降低能量消耗并从而延长电池寿命。

    • A recording medium (D) comprises a file system area (FSA), a data area (DAA) and an initial defect management area (DMA). A system comprises a drive (DR) for writing data (DA) to or reading data (DR) from the data area (DAA) or the defect management area (DMA), and a host (H) for sending data (DA) to or for receiving data (DA) from the drive (DR) when the drive (DR) is in a mounted state wherein a file system (FS) in the file system area (FSA) is available to the host (H). The method of accessing such a recording medium (D) detects (S1) whether a shortage of free space in the defect management area (DMA) is to be expected, and if yes, allocates (S2) supplemental defect management area (SDMA) at the cost of the data area (DAA). The file system (FS) is adapted to reflect the latest state of available data area (DAA) and the allocated supplemental defect management area (SDMA). The file system (FS) is adapted during an adaptation period related to a mounting or an unmounting phase wherein the host (H) mounts or unmounts the drive (DR). The host (H) unmounts or releases the drive (DR) when no further data has to be exchanged between the host (H) and the drive (DR).
    • 记录介质(D)包括文件系统区域(FSA),数据区域(DAA)和初始缺陷管理区域(DMA)。 一种系统包括用于从数据区(DAA)或缺陷管理区(DMA)向数据(DA)或数据(DR)读取数据(DA)的驱动器(DR)和用于发送数据(DA)至 或者当驱动器(DR)处于其中文件系统区域(FSA)中的文件系统(FS))可用于主机(H)的安装状态时从驱动器(DR)接收数据(DA)。 访问这种记录介质(D)的方法检测(S1)是否期望缺陷管理区域(DMA)中的空闲空间不足,并且如果是,则将(S2)补充缺陷管理区域(SDMA)分配在 数据区的成本(DAA)。 文件系统(FS)适于反映可用数据区(DAA)和所分配的补充缺陷管理区(SDMA)的最新状态。 文件系统(FS)在与安装或卸载阶段有关的适应期间进行调整,其中主机(H)安装或卸载驱动器(DR)。 当主机(H)和驱动器(DR)之间不需要更换数据时,主机(H)卸载或释放驱动器(DR)。
