The adjustable wall mounted fan is a device comprising a frame, a mounting plate, a detent, and a positioning device. The frame, mounting plate, and a fan are mounted on the wall. The positioning device raises and lowers the fan vertically and the detent is used to hold the fan is position. The adjustable wall mounted fan is used to improve ventilation in a room.

Adjustable wall mounted fan

A head for writing a plurality of bands. The bands have magnetic transitions onto a magnetic media ( ). The magnetic media ( ) travels in a preselected direction. The head includes a body support structure ( ) and a plurality of write elements ( ). The write elements ( ) have a fixed alignment in the body support structure ( ) that is substantially perpendicular relative to the travel direction of the magnetic media ( ).

Servo write head

Peak detection is conducted by converting a continuous waveform into discrete samples. The discrete samples are evaluated to identify three points near a peak of the continuous waveform. After the three points near the peak are identified, they are stored in a discrete domain data structure which is used in conjunction with a table generated from a continuous transformation function in order to identify an accurate peak amplitude and time.

A multi-track servo recording head includes a multi-tip write core for simultaneously writing a plurality of tracking signals on magnetic storage media. The magnetic recording head may include an optical edge sensor and a magnetic edge sensor for sensing the position of the recording head relative to the edge of the storage media. Additionally, a read core is provided to detect the longitudinal position of the storage media relative to the recording head during media transport.

System for recording track-centering servo signals on multi-track

This invention is directed to a method and a circuit for determining a relative phase shift between a data transition and a data separator window which are used to decode data read back from a mass storage device. The data separator windows provide a time interval in which a data transition must occur in order to be properly interpreted. This is accomplished by delaying the occurrence of the data transition, thereby shifting it toward the trailing edge of the data separator window, to determine if the delayed data transition occurs late within the data separator window. At the same time, the occurrence of the data separator window is delayed, thereby shifting the leading edge of the data separator window toward the data transition, to determine if the data transition occurs late within the data separator window. By delaying the data separator window and the data transition by known, predetermined amounts, a phase shift between the data transition and a particular data separator window in which it occurs can be determined. It is also an object of this invention that if the data transition does not occur within the delayed data separator window or the delayed data transition does not occur within the data separator window, the data transition will be dropped from the data stream and a data read error will have occurred.

A multi-track servo-recording format includes servo zones defined longitudinally by stripes extending across the width of a storage member. Track centering signals are provided within each servo zone for locating the center of each data track on the storage member. Track-identifying indicia are provided at the beginning and end of the storage member and in each written track.
