Aspects of the apparatus which affect the density of the dots that make up the image include such things as variations and randomness of the intensity and frequency of the laser output, and variations in the output of the fiber optics which can vary from fiber to fiber and even within a single fiber as it is moved during the writing process. Variations in the finish of the drum surface as well as drum runout and drum bearing runout and variations in the parallelism of the translation of the printhead with respect to the axis of the drum will also affect the density of the image dots. The difference in the distance between the ends of individual fibers and the drum surface also affects image density because of the fact that the end of the fiber bundle is flat while the surface of the drum is curved. Temperature variations in the printhead due to the ambient temperature of the machine as well as the fact that the writing process itself heats the printhead also influence the image density.
Variations in the print medium elements, such as variations in the thickness of the donor and receiver elements as well as the various layers that are a part thereof, can also affect the image density as it is being written. Computer virtualization is a technique that involves encapsulating a physical computing machine platform into a virtual machine that is executed under the control of virtualization software on a hardware computing platform, or “host.” A virtual machine has both virtual system hardware and guest operating system software. Virtual system hardware typically includes at least one “virtual disk,” a single file or a set of files that appear as a typical storage drive to the guest operating system. The virtual disk may be stored on the host platform or on a remote storage device. Typically, a virtual machine (VM) uses the virtual disk to store the guest operating system, application programs, and application data.
In a virtualized environment, application programs executing on the VM access the physical disk space via a virtualization stack. The virtualization stack includes multiple software layers (referred to herein as the “logical layers”) above the ultimate physical storage layer, the physical disk. Logical layers of the virtualization stack include the guest operating system, the hypervisor and the virtual machine file system (VMFS) driver. Each logical layer is associated with a data block layer that maintains and tracks the allocation of logical data blocks in response to requests received from the applications executing on the VM. Translation mechanisms in each logical layer allow for managing the relationships between data blocks

 view of the apparatus which affect the density of the dots that cause up the image include such thing as pas seul and randomness of the intensity and frequency of the laser output, and variations in the output of the character optics which can vary from character to roughage and even within a single fiber as it is moved during the writing process. Variations in the coating of the drum surface as well as brake drum runout and drum bearing runout and variations in the parallelism of the translation of the printhead with esteem to the axis of the drum will also affect the density of the picture dots. The difference in the distance between the ends of individual fibers and the drum open also affects image density because of the fact that the end of the fiber bundle is flat while the surface of the drum is swerve. Temperature variations in the printhead due to the ambient temperature of the machine equally well as the fact that the writing procedure itself heat the printhead also influence the picture concentration. 
 Variations in the print medium element, such as variations in the thickness of the donor and receiver elements as well as the various layers that are a part thereof, can also affect the image density as it is being write. calculator virtualization is a proficiency that involve encapsulating a physical computing car platform into a virtual machine that is executed under the control of virtualization software on a hardware computing platform, or “ host. ” A virtual machine has both virtual organization hardware and guest operating organization software. Virtual system hardware typically includes at least one “ virtual phonograph record, ” a single file or a stage set of files that look as a typical storage campaign to the guest operating system. The virtual magnetic disk may be stored on the horde platform or on a outside storage device. Typically, a virtual machine (VM) uses the virtual disk to store the guest operating arrangement, application programs, and lotion data. 
 In a virtualized environment, application programs executing on the VM access the physical disk quad via a virtualization stack. The virtualization stack includes multiple software layers (referred to herein as the “ logical layers ”) above the ultimate forcible storage layer, the physical disk. Logical layers of the virtualization stack include the node operating system, the hypervisor and the virtual machine file system (VMFS) driver.
