一种用于可变模式多媒体数据对象存储设备的方法和装置。大的数字对象能在约一分钟内被快速下载。数字对象可以以实时速度被使用或被回放。使用或回放消耗最小功率，允许磁盘支持工作在电池电源上的便携式设备。存储设备使用多磁盘转速来支持多种工作模式。存储设备工作在至少两种磁盘驱动器工作模式下，支持用于写入的快底板转速和用于读取的较慢底板转速。多转速与磁头部件(106)一起工作，磁头部件被配置成带有用于读取的至少一个磁头(202)和用于写入的多个磁头(204)。当写入时，磁盘以较快的转速自旋。当在使用或回放模式时，磁盘以较低的、节约功率的转速自旋。 A method and apparatus for a variable mode multi-media data object storage device. Large digital objects can be quickly downloaded in approximately a minute. The digital objects can be utilized or played back at real-time speeds. Utilization or playback consumes minimal power, allowing the disk to support portable devices operating on battery power. The storage device uses multiple disk rotation speeds to support multiple modes of operation. The storage device operates in at least two modes of disk drive operation, supporting a fast platter rotation speed for writing and a slower platter rotation speed for reading. The multiple rotation speeds operate in conjunction with a head assembly configured with at least one head for reading and multiple heads for writing. When writing, the disk spins at the faster rotation speed. When in utilization or playback mode, the disk spins at the slower, power conserving rotation speed.
