  • Patent number: 9773007
    Abstract: Systems, methods, and computer readable storage mediums for optimizing performance in a storage system. A volume may be mapped to an anchor medium through an indirection layer. When a snapshot is taken of the volume, the allocation of a new anchor medium is delayed until a write operation targeting the volume is received. When a write operation targeting the volume is received, a new anchor medium may be allocated for only a portion of the volume corresponding to the portion of the volume which is targeted by the write operation. Also, when a snapshot is taken of the volume, read optimization operations are performed only the portions of the volume which have changed since the previous snapshot.

    Abstract: According to an embodiment, there is provided an information recording apparatus, such as a digital camera, arranged to record information on a detachably mountable storage medium, such as for example to record video data on the storage medium. In one version of the apparatus, when a connection of an AC adapter is cancelled, the storage medium is detected by a storage medium detection unit, and in a case where the storage medium is not mounted to the mounting unit, a warning is issued, for example in an audio output unit or a display unit. Accordingly, the user can find out that the storage medium is not mounted before the digital camera has been brought outside for use. Thus, it may be possible to prevent a failure in which the user first realizes that they forgot to mount the storage medium only when they are already away from home.

With this arrangement, the present invention provides a super-resolution optical recording medium in which a region on which medium identification information is recorded and a region on which content information is recorded are different in track pitch and in which a reproduction error hardly occurs when reproduction shifts from the region on which the medium identification information is recorded to the region on which the content information is recorded.

  • Patent number: 8599658
    Abstract: A method for 3D recording of data on a medium formed from a transparent photosensitive material including at least one dopant. The method includes a first step of calibrating and checking a pulsed light source including calibrating the number of pulses, the level of fluence of each pulse emitted and the rate of the pulses and a step of inscribing an area of the material. The fluence of each pulse emitted, the number of pulses and the rate of the pulses are suitable for irradiating the material in the area so as to form fluorescent clusters stabilized from the dopant while minimizing the modification of the refractive index and the absorption coefficient of the medium in a wavelength range from visible to near infrared.
