An operating method of a storage device, the method including; loading journal data from a non-volatile memory device, identifying a cache allocation flag included in the journal data, and restoring meta data corresponding to the journal data to a storage controller in response to the cache allocation flag. Here, the cache allocation flag is a first flag when the meta data are allocated to a meta cache of the storage controller, and the cache allocation flag is a second flag when the meta data are stored to a meta buffer of the storage controller.

Storage device and method for restoring meta data thereof

A signal receiving apparatus includes: a tuning unit which has at least one tuner; a communication unit which communicates at least one external device; and a controller which divides an entire channel frequency band to be assigned to the tuning unit and a tunable device, and controls the tuning unit and the communication unit to tune the assigned channel frequency bands if the tunable device is present among the external devices.

Signal receiving apparatus and control method thereof

A disk writer writing servo data on a disk for an HDD. The disk writer includes a reference signal writer writing a reference signal on the disk along a track at a predetermined distance from an edge of the disk; and a servo writer including a reference signal detector detecting the reference signal written on the disk and a writer writing the servo data on the disk on the basis of a position where the reference signal is detected. With this configuration, the present invention provides a disk writer and a writing method thereof, capable of minimizing a positioning error of a start track of an HDD.

Disk writer and writing method thereof

A display device includes a front case; a cathode ray tube mounted on the front case; a main circuit board mounted on the rear side of the cathode ray tube; a circuit board frame, mounted to one among the front case and the cathode ray tube, to support the circuit board; a nonflammable and fire-retardant shield case to contain a fire that may break out in the interior of the display device, while providing a shielding effect which minimizes the radiation of electromagnetic waves generated by the display device and protects the display device from external electromagnetic interference; and a rear case that is combined with the front case to encase the interior of the display device. A top surface of the shield case includes an anode cap shield which protrudes upwardly from the surface to a fixed height to form openings on either side of an anode cap shield. A nonflammable and fireproof plate member having sides which block the openings formed by the anode cap shield is installed under a top plate of the shield case. Thus, the front and rear cases are made of a non-fireproof material, yet UL fire safety requirements are met.
