摘要:
A method optimizing a recording current in consideration of operating temperatures of a hard disk drive and a method of setting a recording density in consideration of tracks per inch (TPI) or adjacent track erasure (ATE) characteristics. The method of optimizing the recording current measures a rate of errors under a test condition corresponding to the operating temperature of a hard disk drive, while changing a recording parameter, selects a recording parameter value corresponding to a smallest rate of errors, and optimizes the recording current for the hard disk drive under operating environmental conditions using the selected recording parameter value.

A method of managing a storage area of a memory device in a memory system is provided. A first data is received. The first data has a logical address to be written to the memory device having a plurality of memory blocks. The first data is classified into one of a hot data and a cold data based on an update frequency of the first data. A memory block is defined into a first storage area and a second storage area based on an amount of charge loss of a memory cell in the memory block. A memory cell of the first storage area has charge loss greater than a memory cell of the second storage area. The logical address of the first data is converted to a physical address of the memory device according to a result of the classifying of the first data. The first data is written to a memory cell having the physical address of the memory device.

Method for driving a plasma display panel, wherein an address reinforcement period is added between an address period and a sustain period, and a scan voltage Vw of positive polarity and a third DC voltage Zdc3 are applied, for inducing floating charges in discharge cells, whereby preventing erratic discharge caused by the floating charges at a high temperature.
摘要:
The present invention relates to a ground structure of a printed circuit board in a microwave oven, where the microwave oven formed with a screw hole at a tip end of a bar extended from a body thereof and having a jumper wire connected to a ground pattern at around a screw hole formed at a printed circuit board while a bolt is screwed to a control panel through a screw hole formed at the tip end of the bar and through a screw hole formed at the printed circuit board are connected by the jumper wire, so that the printed circuit board is automatically connected and grounded to the body of the microwave oven when the printed circuit board is fastened to the control panel, thereby providing a convenience in assembly of the microwave oven and a stability thereto.
