Latest Patents

One of McSweeney's latest patents is titled "Single channel method and apparatus for automatically optimizing insert." This invention involves a single channel circuit and method for the automatic edit optimization of a recording medium. It operates with recorders such as video tape recorders or disc recorders. The technology utilizes the difference between signal outputs from an automatic scan tracking playback head and a record head to provide a difference signal. This signal indicates the RF amplitude fluctuations caused by variations in the data stored on the recording medium. A correction signal corresponding to this difference is stored and used as feedback to normalize the gain of a variable gain amplifier. The single channel is switched at a predetermined rate between circuitry coupled to both heads to develop the correction signal, allowing for precise edit optimization.

Another significant patent by McSweeney is the "Method and apparatus for automatically optimizing the record current." This technique involves a magnetic reference tape pre-recorded with a selected frequency at a precisely known level. A magnetic tape recorder is loaded with this reference tape, and a reference playback level is recovered. The record current is then adjusted until the new playback level matches the reference playback level. This optimization technique can be employed in audio, video, and data recorders, whether analog or digital.
