Abstract: An image recording apparatus which records position information of a place of shooting an image of an object and direction information of the object relative to the recording apparatus. A shooting unit takes images of an object. A receiver receives data for position measurement being transmitted from a satellite and a position information calculator calculates position information using the satellite data. A sensing unit senses a direction of a terrestrial magnetic field and a direction information calculator calculates direction information based on the sensed direction. A transmitting unit transmits the position and direction information to the recording unit which records the position and direction information on a recording medium together with image data corresponding to the taken images. The position and direction information may then be displayed together with the images when the images are reproduced.

Abstract: A removable apparatus for use in a digital recording/reproducing device, for outputting position information, and a digital recording/reproducing device having the same. The removable apparatus has a global positioning system (GPS) having a receiver for externally receiving data for position calculation, a calculator for calculating the position information using the data for position calculation, a connecting portion comprising a fixing portion removably secured to an external device and a transmitting terminal for transmitting the position information to the external device, and a transmitter for transmitting the position information calculated by the calculator to the external device connected to the fixing portion through the transmitting terminal. Preferably, the GPS terminal further includes a power supply for supplying a driving power to the receiver, the calculator and the transmitter.

Abstract: An automatic clock signal phase adjusting circuit for use with a digital magnetic recording and reproducing apparatus adopting a partial response class IV coding method. The automatic clock signal phase adjusting circuit comprises: a pattern detection circuit for detecting at least one of patterns "1, 0, -1" and "-1, 0, 1" from a reproduced signal; a level detection circuit for detecting the levels of the reproduced signal in effect when the pattern detection circuit detects 0's; a clock reproduction circuit for reproducing a clock signal from the reproduced signal; and a phase adjustment circuit for adjusting the phase of the clock signal reproduced by the clock reproduction circuit based on the output signal from the level detection circuit.
