Abstract: A structure is provided that prevents damage to an HDD and loss of recorded data by prohibiting the hard disk from being shifted to the active state in a state in which there is a problem with an environment. On the basis of detection information of each of sensors such as a fall sensor and a temperature sensor, it is determined whether or not data recording or a playback process utilizing the hard disk can be executed safely. The hard disk is caused to be shifted from being in a suspended state to being in an active state on condition that it is determined that safe data recording or playback is possible, and a data recording and playback process utilizing the hard disk is executed. By using this structure, the hard disk is prevented from being shifted to being in the active state in a state in which there is a problem with the environment, for example, in the case of falling, the case of high temperature or high humidity, or the like, and damage to the HDD and loss of recorded data can be prevented.

Abstract: A recording device which records data onto a recording medium includes a nonvolatile memory storing and holding data on a free capacity of the recording medium, and a control unit controlling the data recording. The control unit determines the free-capacity data stored in the nonvolatile memory based on the total capacity of the recording medium when power is turned on. When the determination result indicates that a value of the free-capacity data stored in the nonvolatile memory does not exceed a value of the total capacity of the recording medium, the control unit records the data onto the recording medium with reference to the free-capacity data. When the power is turned off, the control unit updates the free-capacity data so as to reduce the value of the free-capacity data by as much as an amount of the data recorded onto the recording medium.

Abstract: To reduce the occurrence of fragmentation when variable-bit-rate digital data is recorded on a continuous area of unit periods. When the amount of data in the buffer memory is larger than that for one unit period, the digital data in the buffer memory is read every unit period, and the read digital data is recorded as a continuous area (step S106). When the amount of data in the buffer memory is less than that for one unit period, the amount of data is estimated from the time corresponding to the amount of data less than that for the unit period and the length of the unit period (step S112). The digital data of the unit period is recorded on a recordable area in which the estimated amount of digital data can be recorded continuously (step S106).

Abstract: The present invention relates to a recording apparatus and method, a storage medium and a program which allow data for a predetermined playback time to be recorded in a contiguous area on the data storage medium, even when an area in which data cannot be recorded exists on the data storage medium. While a stream unit for a predetermined playback time is being recorded on a storage medium 102, when a recording error occurs, a controller 138 searches for a contiguous blank area greater than the recording capacity of a contiguous recording area in which the stream unit is being recorded. Under the control of the controller 138, a drive 136 secures, in the beginning of the found area, an area having the same capacity as the data amounts of an IL auxiliary area and a recorded stream unit, records an unrecorded stream unit, and then copies the recorded stream unit. The present invention is applicable to video cameras.
