1. A portable device that is battery operated and stores data for retrieval, the portable device comprising:
- a hard disk drive having a first storage capacity for storing data in the portable device,a solid-state memory module having a second storage capacity, smaller than the first storage capacity, for temporarily storing blocks of data being retrieved,a output module for the blocks of data temporarily stored by the solid-state memory module,a copy module for intermittently copying blocks of data from the hard disk drive to the solid-state memory module for outputting by the outputting module,a primary battery providing energy to the portable device, but not directly to the hard disk drive,a supplemental energy storage device providing energy in intermittent periods to the hard disk drive during copying of the blocks of data from the hard disk drive to the solid-state memory module, anda charger module for charging the supplemental energy storage device, from the primary battery, between the copying of the blocks of data.

Abstract
A battery-operated portable electronic device has a primary battery to provide energy to low current circuitry of the portable device, and a supplemental battery to provide intermittent bursts of energy to other components of the portable device. A charging device charges the supplemental battery from the primary battery. An electronic device employing the battery system may have a battery compartment for the primary battery, which can be an AAA, AA, C, or D size battery.

11. A portable media player comprising:
-
a hard disk drive having a first storage capacity for storing media data in the media player, a solid-state memory module having a second storage capacity, smaller than the first storage capacity, for temporarily storing blocks of media data, a player module for playback of the blocks of media data temporarily stored by the solid-state memory module, a copy module for intermittently copying blocks of media data from the hard disk drive to the solid-state memory module during the playback, a primary battery providing energy to the portable media player, but not directly to the hard disk drive, a supplemental energy storage device providing energy in intermittent periods to the hard disk drive during copying of the blocks of media data from the hard disk drive to the solid-state memory module, and a charger module for charging the supplemental energy storage device from the primary battery between the copying of the blocks of media data.
