digital data storage device
An instance of DigitalDataStorageDevice is an ElectronicDataStorageDevice intended to be used for storing data (information) in some digital (discrete bit) encoding scheme designed for interpretation by computers.
Relationships      
Parents electronic data storage device An instance of ElectronicDataStorageDevice is a DataStorageDevice intended to be used for storing data (information) in some encoding scheme designed to be interpreted by electronic devices.
Children compact discAn instance of CompactDisc is a flat, disc-shaped DigitalDataStorageDevice that has a reflective medium on at least one side, in which a laser is used to write and read bits of data.
 computer diskA type of DigitalDataStorageDevice that is disk-shaped and is read while being spun in a DiskDrive.
 digital audio tape cassetteAn instance of DigitalAudioTapeCassette (DAT) is a DigitalDataStorageDevice consisting of RecordingTape enclosed in a plastic case, intended primarily for storing sound (audio) data in some digital encoding.
 DVDAn instance of DVD (Digital Versatile Disk) is a disc-shaped DigitalDataStorageDevice similar to a CompactDisc, but with a larger storage capacity.
 hard disk driveThe primary computer storage medium, which is made of one or more aluminum or glass platters, coated with a ferromagnetic material. Most hard disks are fixed disks, which are permanently sealed in the drive.
 internal digital data storage deviceA type of DigitalDataStorageDevice that is installed in a Computer and not readily removable.
 optical discThis Class comprises several subclasses of disc-shaped data storage devices. Unless otherwise indicated, instances of all of these classes are generally consist of plastic discs incorporating one or more reflective layers of gold or aluminum, which is pitted by a laser to encode data.
 read only memory data storageA DigitalDataStorageDevice on which it is not possible to write or alter any DigitalData except during its fabrication.
 removable digital data storage deviceA type of DigitalDataStorageDevice that can be temporarily installed in a computer and is readily removable.
 rewritable data storageA DigitalDataStorageDevice on which the stored DigitalData can be altered or deleted, e.g. CD-RW.
 solid state data storage deviceA type of DigitalDataStorageDevice which can be read with no moving parts.
 write once data storageA DigitalDataStorageDevice on which the DigitalData once written can not be deleted or altered, e.g. CD-R, DVD-R.
